AQCL5A410SE is a quantum cascade laser driver with single ended input control. The AQCL5A410SE is a chassis mount electronic module designed for driving QCLs. It delivers ultra-low noise current and still preserves a wide modulation bandwidth. The AQCL5A410SE comes with protections for over-voltage, under-voltage, over current, and over temperature. To monitor the working status of the laser driver, there is a control loop good indication pin, LPGD; and the output current monitor pin, LIO.
