Fandango DPSS laser
14 June 2011
Cobolt, Swedish manufacturer of low-noise DPSS lasers, has released a higher power model of its 515nm solid-state laser. The Cobolt Fandango is now available with up to 150mW CW output power from the same small package. It is not only perfectly suited for power demanding fluorescence analysis applications such as confocal microscopy, high-speed plate reading and single molecule analysis, but now with even higher output power, as a general all solid state alternative to bulky Ar+ gas lasers.
The Cobolt Fandango is a continuous-wave solid-state laser operating at a fixed wavelength 515nm and with output powers of 25mW, 50mW, 100mW and now 150mW. It 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).
The laser is manufactured using Cobolt's HTCure technology in a compact (50 x 50mm) and hermetically sealed package, which provides a very high level of immunity to varying environmental conditions and exceptional reliability. Lasers built using the HTCure technology have been shown to withstand multiple 60G mechanical shocks in operation. They can be exposed to extreme temperatures (>100°C), and are insensitive to pressure and humidity.
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 (RS232) or analogue interfaces.
