A laser driver is an electric module to drive one or multiple laser diodes with low noise and high efficiency for applications such as DPSSL, EDFA, and fiber lasers. The laser driver designed and produced by our company (ATI) has high quality and long service lifetime. And in our company, there are various types of laser drivers, such as ATLSXA212 series, ATLS_XXX_103 series, ATLSXA201D series and so on. The following photo is a typical one of ATLSXA212 series laser drivers.(more)

In order to drive laser diodes, our company (ATI) has designed and produced laser drivers with high voltage and constant current. The laser drivers feature high efficiency, high stability, low noise and compact size. And because of high efficiency, they don’t need heat sinks during normal operation. Figure 1 is the ATLS1A212D laser driver, which is a typical one of our laser drivers.(more)

Since the laser was found in 1960, it has been becoming more and more popular in modern industry, communication, national defense and other fields. And in order to meet the need for driving laser diodes, our company (ATI) has designed and released a series of laser drivers, such as ATLSXA212, ATLSXA201D and so on. As shown in Figure 1, ATLS1A212D laser driver is a typical one of the ATLSXA212 series laser drivers. It has a maximum output current of 1A and also has a wide range of power supply voltage from 4.5V to16V.(more)

ATLS3A212 laser driver is an electric module with 3A constant current, which is designed and released by our company (ATI). This laser driver has full swing output voltage, from 0.8V to VPS. It has been used to drive one or multiple laser diodes with high efficiency and low noise. Figure 1 is the photo of the ATLS3A212laser driver.(more)

ATLS4A214 laser driver is an electric module with high voltage and constant current, which is used to drive laser diodes in many fields, such as modern industry, communication, national defense and so on. This driver has a wide input voltage range from 5V to 16V, a maximum output current 4A and a wide modulation bandwidth. Figure 1 is the physical photo of the ATLS4A214 laser driver.(more)

The ATLS500mA212 is a laser driver with low output noise and high efficiency. It is designed to drive one or multiple laser diodes for DPSSL, EDFA, or fiber lasers. This laser driver features high current stability, low output noise, and small size, as shown in Figure 1, and so on. And there are two package methods available: DIP and SMT packages.(more)

TEC module is short for thermoelectric cooler, and is also called Peltier cooler, or TECs. There are multiple pairs of Peltier elements inside the two ceramic plates of TEC modules. One ceramic plate dissipates heat and the other side absorbs heat. The TEC module is perfect for temperature control applications.(more)

The ATLS4A214D laser driver is an independent research and development product of ATI. The laser driver features that the power supply voltage VPS range is from 5V to 14V, the full swing output voltage is from 0V to 75% VPS (input voltage) and the maximum output current is 4A. And it also has a wide output voltage range, 0~15V, which can drive one or multiple laser diodes at the same time and also control the current (up to 4A) well.(more)

There are multiple series of Thermal cycling TEC modules in our company. ATE1-TC-71 TEC modules come with a longer thermal cycling operational life than standard TEC modules. These thermal cycling TEC modules are designed for temperature cycling applications. In these applications, TEC modules are exposed to demanding physical stresses when the TEC modules shift from heating to cooling, and this can reduce the operational life of standard TEC modules. Therefore, thermal cycling TEC modules will be a perfect solution. ATE1-TC-71 series TEC modules have two products, ATE1-TC-71-5R5AS and ATE1-TC-71-7R8AS. There are totally 71 pairs of Peltier elements. The maximum currents through the TECs are 5.5A and 7.8A respectively; the maximum input voltage of both TEC modules is 9V. The size is very compact, 30*30mm.(more)

ATE1-TC-127 series thermal cycling TEC modules come with high input voltage, 17.5V. There are several types of thermal cycling TEC modules in this series. The output currents are 5.5A, 5.7A, 8.5A, 7.8A and 12.1, each corresponding to a TEC module respectively. The temperature differences can be 72°C, 72.5°C and 74.5°C. The dimensions are not the same either. These thermal cycling TEC modules are designed for temperature cycling applications. The operational life of standard TEC modules will be largely reduced when the TEC modules shift from heating to cooling. However, the thermal cycling TEC modules perform well during the shift and the service life is much longer than standard TEC modules. Therefore, it would be a perfect selection when the application needs TEC modules with long operation life.(more)
