Cobolt released a higher power model of its Cobolt Twist 457nm laser on the 05-01 Series platform. With up to 200mW single-frequency CW output power, the new model is perfectly suited to demanding applications in holography, Raman spectroscopy and photoluminescence. The wavelength and optical properties make it ideal as a replacement of bulkier Ar+ lasers. 

The Cobolt Twist is a CW single-frequency diode pumped laser operating at 457nm with a perfect quality TEM00 beam (M2< 1.1). Its proprietary laser cavity design provides ultra-low noise performance of typically <0.2 per cent rms (over 20Hz-20MHz and over 10-40ᵒC), stable single longitudinal mode operation, intrinsically excellent wavelength stability and immunity to optical feedback.

All Cobolt lasers are manufactured using HTCure technology and the resulting compact hermetically sealed package provides a very high level of immunity to varying environmental conditions along with exceptional reliability. Lasers built using the HTCure technology have been shown to withstand multiple 60G mechanical shocks in operation without any sign of degraded performance.
