Laser Diode Controller(LDD605)
The LDD605 laser diode driver is a
combination current and temperature
controller with sophisticated front-panel
menu operation and plain text computer
command interface via ethernet and USB. A
high-precision low-noise current source
drives a wide range of diodes at up to 6 amps.
The precision temperature controller, with
flexible computer-defined PID response,
provides 60 W capacity for a wide range of
TEC devices. The LDD605 is designed for use
with our MOA series of tapered amplifiers
and high-power diodes for lasers and fibre
amplifiers
