This unit
The ILX Lightwave LDC-3714 is a precision laser diode controller delivering selectable 50 mA and 100 mA output ranges with sub-microamp resolution and sub-percent accuracy. Built for research, development, and production test environments, it combines low-noise drive electronics with an integrated 32 W temperature controller and comprehensive laser protection. Dual modulation modes support DC operation and high-bandwidth external modulation up to 1 MHz, while photodiode feedback monitoring enables closed-loop optical power stabilization.
