Quantum cascade laser driver
⠀⠀⠀⠀⠀⠀⠀⠀⠀
Koheron QCL100 is a high-performance current driver designed to drive high-voltage loads such as Quantum Cascade Lasers. It operates as a current sink, allowing the laser anode to be connected to the ground. The QCL100 driver provides a compliance voltage adjustable up to 15 V and an adjustable precision current limit. The board features a 5 MHz modulation input and a 10 Hz trimming input. It is supplied from a single 24 V input and comes with an aluminum base plate
