Cobolt has introduced a higher power model of the Cobolt Twist 457 nm on the 05-01 Series platform. With up to 200 mW single-frequency CW output power, the Cobolt Twist is perfectly suited to demanding applications in holography, Raman spectroscopy and photoluminescence. The wavelength and optical properties makes it ideal as a replacement of bulkier Ar+ lasers.
The Cobolt Twist is a continuous-wave single-frequency diode pumped laser (DPL) operating at 457.0 nm in a perfect quality TEM00 beam (M2< 1.1). A proprietary laser cavity design provides ultra-low noise performance of typically <0.2 % rms (over 20 Hz-20 MHz and over 10-40 ℃), stable single longitudinal mode (SLM) operation, intrinsically excellent wavelength stability and immunity to optical feedback.
Some highlights of the 200 mW Cobolt Twist 457 nm are:
- High power, single frequency CW diode pumped lasers: 355 nm – 1064 nm up to 3 W.
- 355 nm, 457 nm, 491 nm, 532 nm, 561 nm, 660 nm, 1064 nm
- CW DPSSLs with output power up to 3 W
- High quality laser beam, TEM00
- Ultra-robust, hermetically sealed packages
- Low noise, less than 0.1% rms
- Immunity to optical feedback
- Perfect for interferometry, Raman, optical tweezers, super resolution microscopy, laser doppler velocimetry
- Up to 24 months warranty
