Laser Diode Driver (LDD/ILD)
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 MSA/MOA series of tapered amplifiers and high-power diodes for lasers and fibre amplifiers.
The ILD605 is a variant of the LDD605 that is enhanced with algorithms to autonomously operate the MOGLabs injection lock amplifier (ILA).
