Single frequency lasers by Cobolt

The laser cavities include frequency-selective optics which stabilize the resonator and prevent all but one longitudinal and transversal mode of the laser to be amplified in the oscillator. By combining advanced cavity designs; standing-wave as well as ring-cavities, with a thermo-mechanically stable platform, active temperature control of the complete cavity and robust fixation of miniaturized high precision optics, the Cobolt CW DPSS lasers provide very stable single-frequency or single-longitudinal mode operation over the whole laser lifetime and over a wide range of operating conditions.

The single frequency and single transversal mode operation of the lasers results in extremely narrow laser linewidths (< MHz), low intensity noise of down to <0.1% RMS and a perfect diffraction limited TEM00 beam. Built with HTCure Technology into hermetically sealed packages the lasers deliver stable reliable performance over long lifetimes and in demanding ambient conditions. They are suitable not only for advanced laboratory research but also for integration into analytical instrumentation for applications such as Raman spectroscopy, bioimaging, interferometry, holography and quantum technology research.

Cobolt offer single frequency or SLM laser performance in the 04-01, 05-01 and 08-01 Series.
