Diode Laser Driver ATLS200MA103

ATLS200MA103 is a laser driver in 103 laser driver series, with the maximum low noise output current of 200mA. The noise is ultra low, ≤2.5µVP-P at 0.1Hz to 10Hz.

When this laser driver is powered by a 5V power supply, it will output a voltage range from 1.5V to 4V. The output current of this laser driver can be set by an input voltage linearly or modulated by an external signal of up to 2MHz in bandwidth, which results in a minimum 1μS rise and fall time at the output current. There is a low noise 2.5V reference voltage that is used for setting the output current. This reference can also be used as the voltage reference for external ADCs and/or DACs. 

Two packaging versions are available, DIP package and SMT package. The former can be evaluated by an evaluation boardATLS1A103DEV1.0, which comes with a dummy laser on the board.

Super SMD/SMT Component Enclosure

Sorting, storing and finding a SMD (Surface Mount Device) - sometimes called SMT (Surface Mount Technology), components is not easy, this is because they are so tiny and there are so many kinds of them: different sizes, values, types, etc. There is a good news: a special enclosure has been developed and made available by Analog Technologies, Inc., for solving this problem. The product is called Super SMD/SMT Component Enclosure. It is a big box with a big cover, underneath, there are 128 compartments, each of them has a dedicated lid; each lid has a small handle for opening and closing the lid and, under the handle, there is a legend area for marking the values of the parts inside. The lid is locked into its position so that the small SMD/SMT parts won't be leaked out, see photo below. 

After using, close all the small lids and the big cover which has resilient foam pad. When the big cover closes, this foam (shown in yellow) pad presses all the small lids downward so that they remain locked even under severe shocking and vibration, see the drawing:

Therefore, this enclosure is not only being a convenient solution for storing and sorting small parts, but also a reliable means for transporting them. The photos below are the views from outside, underneath, and inside. The most suitable parts to store into this enclosure are: SMD/SMT resistors, SMD/SMT capacitor, SMD/SMT inductors, SMD/SMT ICs (Integrated Circuits), small mechanical parts, etc. 

By using this Super SMD/SMT Component Enclosure, you can keep usually clustered bench top clean and organized, you can put ATI kits like the below:

By doing this, eliminate all "fatal" mistakes when using a wrong value components in a critical place of a circuit. Meanwhile, it is quite convenient to use these kits. See the figure below:

The source of the product, Analog Technologies, Inc., is a reliable and reputable company. It has been in business for > 17 years and offers > 100 different products. In addition to the laboratory tool type products, they also have laser drivers, TEC (Thermo-Electric Cooler) controllers, TECs (Thermo-Electric Coolers), high precision and high stability thermistors, customized heat sinks, TEC assemblies, etc., for photonic, display and biotech industries.

Reduce Risk of Burning Electronic Equipments with NTC Thermistors

Thermistors are temperature- sensing elements. They are made up of semiconductor material and are largely used in electrical parts and electronic items. The materials used in thermistors manufacturing are capable of indicating large changes in resistance in proportion to small changes in temperature. Thus thermistors are regarded as highly incredible tool to measure accurate drop and rise in temperature. The sensitive materials used can measure even the slightest change in resistance and temperature.

 

NTC Thermistors are non-linear resistors. They are radial leaded discs or similarly assembled in order to provide high performance with durable result. The resistance of this kind of thermistor decreases as there is a rise in temperature. The resistance through the thermistor can be measured by passing small and measured direct current, which also predicts drop in the voltage. Significant uses of NTC thermistors can be as follows:

 

NTC thermistors are generally designed to protect other electronic components from a high and sudden inflow of current.

These high performance NTC thermistors are known to work well with devices like TEC controllers, and TEC modules.

NTC thermistors are designed in a way so that it is capable of building a high stability low drift temperature control system.

The NTC thermistors are mainly glass coated, which make them the most sensitive, precise and low drift sensors.

NTC thermistors have proven to be extremely reliable and inexpensive.

NTC thermistors are essential and their presence is critical for the protection of electronic components within any product that has a circuit.

 

The selection of NTC thermistor should be dependent upon the application of the gadget and maximum continuous current that results due to voltage. The range of thermistors available with Analog Technologies is made out of good quality material and can be efficiently used for your daily requirement.

AC input laser driver usually comes with a larger size than DC input laser driver. AAS30A5V1 is one of our AC input laser drivers which are used for driving diode lasers with high current and high stability, such as fiber lasers, diode laser bars. 

The AC input laser driver AAS30A5V1 has high efficiency, up to 76%. The input voltage is wide, from 88VAC to 264VAC, with a wide output voltage from 0V to 5V. The high speed digital modulation is 5 kHz. There are configurable output current and voltage limit, as well as digital modulation valley current. There is also an over temperature protection circuit inside the laser driver. The operating temperature is from -20 to 50°C.

Selection of Laser Drivers

ATI is a company specializing in designing and releasing laser drivers, which can be used to driver laser diodes with high stability, low noise, and high power efficiency.  And there are many kinds of laser drivers. If you use laser diodes with high power or current, you can select the dual mode laser driver; if you need a laser driver with low noise, you can choose the ultra-low noise laser driver. In addition, when laser drivers and TEC controllers are used together, you can obtain high performance low cost diode laser modules. Figure 1 is the typical one of the dual mode laser drivers.

The LDA1-CP1 laser driver has a maximum output current 2A and current output noise: 0.05%. During normal operation, it generates little amount of heat, so there is no need of heat sinks. This laser driver comes with two separate input voltages to set and monitor the output current and laser power.

ATLS2A202D Laser Driver for Driving Laser Diodes

With the development of science and technology, laser drivers have been used more and more widely. And the demand of laser drivers is also growing. In order to meet the demand, our company (ATI) has designed and released many kinds of laser drivers with high quality and compact size. As shown in Figure 1, the ATLS2A202D laser driver is a typical one of our laser drivers with a maximum output current 2A 

Figure 1. The photo of the ATLS2A202D laser driver

During operation, this laser driver has high efficiency (more than 90%), high stability (100ppm/°C) and zero EMI. It provides DIP package for users. And this laser driver comes with a frequency synchronization, which allows using an external digital signal to synchronize the internal PWM output stage. This function can help eliminate frequency hopping interferences from other electronics when loading multiple laser drivers on the same PCB.

AC Input Laser Driver AAS30A4V2

Laser driver is designed for driving diode lasers. There are two types of laser drivers, DC laser drivers and AC laser drivers.AAS30A4V2 is one of AC laser drivers designed and newly released by ATI.

The AAS30A4V2 AC input laser driver is for driving diode lasers with up to 30A low noise current and high efficiency, ≥76%. The input voltage is wide, from 100VAC to 240VAC. The maximum output current is 30A, which can be set by an analog voltage of 0V to 2.5V, an external potentiometer, or an internal potentiometer, to between 0A and 30A.  This AC input laser driver comes with high stability low noise 2.5V reference voltage, which can be used to set the output current and maximum output voltage. This 2.5V reference can also be used as the voltage reference for external ADCs and DACs, which can be used for monitoring or setting the laser current and maximum output voltage.
