DP-PS Laboratory Diode Driver

(print-friendly format) PDF

For use with MK-11, 81, 82, 85, & 88 lasers

Kigre manufactures a laboratory laser diode driver for use with the MK-88, 85, 82, 81 and MK-11 laser heads. The driver features precision pulsed current operation and supports the HESP family eye-safe laser diode requirements. A USB cable and software are provided so that the customer may use their computer as a laser controller. The driver accepts 20 to 30 volts DC and includes a convenient AC/DC power adapter for universal 100-240VAC operation. The driver also includes ultra-high performance hold-up capacitors for stable pulsed current control up to 110 Amps. Soft-start control, active current limiting, transient filtering, and a mechanical shorting relay provide robust protection for the laser.
