Why and How Should We Choose A Constant Current Laser Driver

Time: 2018-08-03 17:20:43    Click: 167

Why laser diode needs to be driven by a constant current laser driver? A. The laser diode itself is a very vulnerable device, so when it is working, a larger current will cause the laser diode to burn out, and a lower current will not make the laser diode work properly. With a constant current source, the current can be just right and the laser diode can work normally without damage. B. Laser diodes are extremely temperature-sensitive in the operation. The forward voltage of the laser diode decr...(more)

If you need a high voltage power supply in your project and you are new to high voltage power supply, then how do you select a proper high voltage power supply ? At first, determine the output voltage range of the high voltage power supply according to the specific applications. There are positive and negative output voltages. Take ATIs high voltage power supply as an example. The high voltage power supplies come with positive output voltages from 1kV to 60kV, while the negative output voltages...(more)

We have developed multiple series of constant current laser drivers. Such as ATLSxA103D, ATLSxA104D, ATLSxA214D, ATLSxA216D, etc. These laser drivers can be used to drive more laser diodes with high efficiency. They have both a wide input voltage range and a wide output voltage range. The size is very small, but can output high current and high voltage. The real laser diode is very vulnerable in practical applications. We developed a laser driver load assembly, ALLD10A14V. Here is an internal bl...(more)
