High power, single frequency, CW diode pumped lasers

The Cobolt 05-01 Series lasers are continuous-wave diode pumped lasers (DPL) operating at a fixed wavelength between 320 nm and 1064 nm. Single frequency operation provides an ultra narrow spectral linewidth, long coherence length and excellent spectral purity. In the Cobolt 05-iE all-in-one lasers all control electronics are contained in the laser head eliminating the need for an external controller and bringing the trusted laser performance of Cobolt 05-01 Series into a compact, self-contained device. The lasers are designed and manufactured to ensure a high level of reliability.
