Product Overview:

785nm, 600mW VBG Wavelength Stabilized Laser Diode for Raman Spectroscopy Applications

These 785nm, 600mW wavelength stabilized laser diodes provide high ex-fiber output power at a narrow linewidth, stabilized by a Volume Bragg Grating.

The laser diode is optimized for Raman Spectroscopy, and is also used for metrology, sensing, bio-instrumentation, and analytical instrumentation applications. The laser is packaged in an industry standard 14-pin butterfly package, and includes a high power internal TEC for temperature control and laser output stability.

These laser diodes are offered through Laser Lab Source in North America. They are manufactured by RealLight Technology, an industry leader specializing in the research, development, and manufacturing of semiconductor lasers for spectral analysis and pumping applications.

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 diode‘s 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.
