Edmund Optics' fiber-coupled lasers for Raman spectroscopy

Edmund Optics' (Barrington, NJ) Spectrum Stabilized Fiber Coupled Laser Systems were designed as rugged sources for Raman spectroscopy. They offer high powers of 450 mW at three wavelengths of 785nm, 808nm and 976nm.

Both the laser and driver enclosed in a rugged, self contained package. The 100 mm multimode fiber is attached to the laser with a high brightness coupling, and offers a beam divergence of 0.22 NA and maximum bandwidth as low as 0.3nm (full-width half-maximum). The system also incorporates a thermoelectric cooler, TEC controller, and digital on/off modulation.

In addition to being rugged, the system is small and long-lived: the laser system measures 265 x 155 x 100 mm, and the systems expected lifetime is longer than 10,000 hours.
