Product Overview
940nm Laser Diode, Single-Mode Fiber-Coupled
These single-mode 940nm lasers deliver 200mW via single-mode fiber; polarization-maintaining fiber is available optionally. The internal photodiode, thermistor, and TEC ensure stable operating over long operating life-times, and in a wide variety of application environments.
Fully Configured Source System Available
The 940nm laser diode is also available packaged in a preconfigured laser source system with built in mount, control electronics, and remote user interface. See the below for the link.
Important Notes on Operating Laser Diodes:
Electrical Operation: Operating a laser diode above the maximum ratings shown on the data sheet even for very short periods of time can damage the laser diode or reduce its lifetime. They should be electrically biased with a “laser diode driver” class current supply with low electrical noise and protection against voltage and current surges. Laser diodes are very sensitive to electrostatic discharge (ESD). Proper ESD precautions must be taken.
Mounting and Temperature Control: In order to maintain the lifetime of a laser diode, proper heat management is essential. Due to the design of the laser diode, heat is typically dissipated only through the base plate of the diodeโs package. A proper heat conducting interconnection between the diodes base plate and the heat sink must be maintained. Some devices require the use of a thermo-electric temperature controller (TEC controller) to remove the heat from the laser and stabilize the temperature.
