Diode lasers are valuable but vulnerable devices, and when you need to test a new laser driver, it’s better to use a dummy laser. ATI has developed such a dummy laser, i.e. a load assembly for testing laser driver, ALLD10A14V. This load assembly allows a current of up to 10A and the reserve voltage on each diode can be 150V. Moreover, it can bear a current of 100A for a short time, while regular laser diodes only allow a current 1.5 to 2 times higher than the rated value. Therefore, we can see that this load assembly would be stronger and more durable than regular laser diodes.
This load assemble can emulate one or multiple diode lasers. It includes a series of regular laser diodes with configuration switches, which allows users to insert more diodes into the circuit, or short out the diodes by some switches. There are heat sink and fan in the load assembly, which are used to cool down the temperature of the diodes. In order to prevent the assembly being damaged from over temperature, this assembly comes with over temperature detection and shutdown circuit, which will shut down the laser driver when detecting the temperature exceeds 90 degrees.
You can do more with this laser driver load assembly by referring to the datasheet.
