In the process of selecting suitable analog electronic component modules, constant current is a very important factor. To be the best in the field of analog electronics, Analog Technologies, Inc.(hereafter referred to as ATI) has invested a lot to improve the quality of our laser drivers. Finally, through efforts, ATI has developed various kinds of high quality laser drivers, tec controllers and smt kits; Today let me introduce one high efficiency constant current laser controller, whose part No. is ATLS3A202D. Please take a look at its physical photo of this laser driver.(more)

Are you looking for a low noise and constant current laser driver with a compact size? ATLS500MA106 is a best choice for you. This laser driver features ultra low noise and constant 500mA current, which is packaged in a metal enclosure with six sides, blocking electro-magnetic interference from other surrounding electronics.(more)

Diode laser drivers can be categorized by output stage type: PWM type and linear type. The PWM type laser uses a high efficiency PWM output stage as the power output, which features high efficiency but high ripple noise and low speed. When the current is more than 1A, we recommend a PWM mode laser driver. CWD-01-V2-D is one of the PWM type laser drivers.(more)

Do you know what does a laser driver mean, and how to choose a good and high quality laser driver in such a complicated and huge internet? As an engineer engaged in the analog electronics for more than 10 years, let me give you some guidance. First, laser driver is an electronic module designed for driving diode lasers. Then what features or characteristics should a good laser driver have are also very essential, such as constant current, high efficiency, low noise, high reliability, zero EMI, and small package and so on. Today let me introduce one high efficiency constant current laser controller, whose part No. is ATLS2A201. Please take a look at its physical photo of this laser driver.(more)

In recent years, with the rapid development of optoelectronic technology, diode lasers have been widely used in medical, defense, measurement and other fields. The change in ambient temperature directly affects the wavelength of the diode laser. Since the temperature has a great influence on the quality of the diode laser, in the case of a constant current, the laser wavelength will increase by about 0.1nm for every 1°C increase in temperature, and too high a temperature will cause the diode laser to age or even be damaged. The diode laser is a device that is electrically sensitive and expensive, so our controllers must provide monitoring, limiting and overload protection capabilities.(more)

1. Does heat dissipation need to be provided during the use of the laser driver? A. The higher the operating temperature of the laser driver, the greater the loss of its operating efficiency, the greater the noise, and therefore the worse the current stability. Its operating case temperature is −40°C ~ 85°C, We recommend that its working temperature be around 50°C.(more)

The laser driver AAS45A4V2 is designed for driving multiple laser diodes with high efficiency and low noise. Its efficiency is ≥ 76% that saves energy and has low temperature rise. It has a wide input voltage range. This laser driver accepts AC voltage input, from 100V to 240V. It also has a wide output voltage range from 0V to 4V. It has high current output capability. The maximum output current can go up to 45A that can be set by an analog voltage of 0V to 2.5V. The operating temperature is from −20°C to 50°C.(more)

The word "best" sounds so high-end, advanced, and expensive, and should be an outstanding one. People are often troubled by "best", so, what is the best?(more)

We have developed a series of constant current CW laser drivers ATLSxA202D. The laser drivers include: ATLS500MA202, ATLS1A202, ATLS2A202, ATLS3A202, ATLS4A202, and ATLS6A202. In order to use the laser driver more conveniently, we developed an evaluation board for ATLSXA202D series diode laser drivers specially. The evaluation board is designed to evaluate the functions and basic specifications for ATLSXA202D.(more)

Analog Technologies, Inc is a company specialized in laser and TEC technology. Therefore, there are various kinds of laser drivers for customers to choose. Based on the power input type, ATI’s laser drivers are divided into AC input modules and DC input modules. For the DC input modules, we have both linear type and switch type. Today, I will introduce one high voltage constant current laser driver, whose part No. is ATLS8A216, which is the most popular among customers.(more)
