Product Description
The LDD-20450 is an economic QCW laser diode
power is available with the supplied heatsink
driver module designed to provide high current
and forced air flow. By using a custom coo-
pulses to drive laser diodes in various applica-
ling solution, the power can be increased up to
tions. It delivers output currents up to 450 A
3000 W. Several safety features are integrated
and pulse widths variable from 10 to 1000 μs
to protect both laser diode and driver.
operation. Up to 1500 W average output
