Price starting at

¥ 1980.00

YSLDU01115X-14 is a low noise laser diode driver with integrated TEC, designed for 14 pin butterfly laser diodes with Pump (Type 1) and Telecom (Type 2) pinouts.

  • Low noise LD driver with low PPM maintains stable laser parameters over the wide temperature range.
  • Fully digital design is making easy to control, tune, optimize and tweak laser output parameters.
  • Wide range of integrated protections provides stable workflow over the unpredicted hazards.
  • Cross-platform and easy to use software allows to control laser parameters from the operating system of your choice.
  • Industry proven SCPI command set provides easy integration to existing infrastructure or building new setups with non-standard requirements.
  • Rigid aluminum shell available for harsh environment installations.
