MK2-PS Laboratory Diode Driver

(print-friendly format) PDF

For use with the Kigre MK-2 laser

Kigre manufactures a laboratory laser diode driver for use with the MK-2 laser. The driver operates from a standard USB port (5Vdc) and features precision pulsed current output for the laser. The driver accepts 2 to 18 volts DC input and includes a selectable 100mA/500mA input current setting to protect sensitive USB ports and/or batteries. The driver also includes ultra-high performance hold-up capacitors for stable pulsed current control up to the 8.5 Amps required by the MK-2 laser. Soft-start control, active current limiting, and advanced laser transient protection circuitry are included.
