Cobolt has released a higher power model of its 515nm solid-state DPSS laser. The Fandango, now available with up to 100mW CW output power from the same small package, is well suited to power-demanding fluorescence analysis applications such as confocal microscopy, high-speed plate-reading and single molecule analysis. The higher output power also makes the laser suitable as a general, all-solid-state alternative to bulky Ar+ gas lasers.
The Cobolt Fandango is a continuous-wave solid-state lasers operating at a fixed wavelength 515nm and with output powers of 25mW, 50mW and 100mW. Built into a hermetically sealed compact (50 x 50mm) package using the company's HTCure technology for extreme robustness, the Cobolt Fandango is a single longitudinal mode laser, with very low noise (<0.3 per cent rms), narrow spectral line width (typically <30MHz) and exceptionally high beam quality (M2<1.1).
Lasers built using the HTCure Technology have been shown to withstand multiple 60g mechanical shocks in operation without any sign of degraded performance. They can be exposed to extreme temperatures (>100oC), and are insensitive to pressure and humidity. HTCure Technology is an advanced manufacturing technique for high-performance solid-state lasers that can provide exceptional reliability and performance for today’s demanding applications.
515nm is the final missing link to a compact all solid state replacement of Argon ion lasers for use in fluorescence applications, in particular for the excitation of YFP, Alex 514 and Oregon Green. Cobolt now offers a complete range of high performance DPSS lasers to the fluorescence based bioanalytical industry to replace argon and krypton ion lasers: 457nm, 473nm 491nm, 515nm, 561nm, 532nm and 594nm lasers are currently available at output powers from 10 to 300mW.
The laser controller is an ultra-compact unit in either a CDRH version or OEM version. It is built on a robust platform with mounting holes for convenient installation and optimum heat dissipation. It is remotely controllable for operation and monitoring of the laser system via digital (RS-232) or analogue interfaces.
