Description

The Laser Space 785 nm Grating-Stabilized Laser Diode is a volume-holographic-grating (VHG) laser ideal for Raman spectroscopy applications. This laser diode is housed in a 14-Pin, hermetically sealed butterfly package that allows the laser to be temperature controlled. This laser diode produces a wavelength-stabilized spectrum with a typical output power of 600 mW, and the output is coupled to 1.0 m of FC/PC-terminated multimode fiber.

Features:

785nm wavelength
0.6W output power
△λ<0.1nm

Applications:

Raman Spectroscopy
Sensing
Medical
