Cobolt Fandango at 515nm

Share this on social media:

Cobolt  has released a higher power model of its solid-state laser at 515nm. The Cobolt Fandango, now available with up to 50 mW CW output power, is suited for power demanding fluorescence analysis applications such as spinning-disc confocal microscopy and high-speed plate reading.


Built on the Cobolt DPSS laser platform, the Cobolt Fandango is a single longitudinal mode laser with very low noise, narrow spectral line width and exceptionally high beam quality in a compact hermetically sealed package.


Cobolt single-frequency lasers are based on the proprietary Cobolt PPKTP frequency conversion technology, with narrow spectral bandwidth (typically <30 MHz). The Cobolt Fandango features low noise (<0.3 per cent rms) and excellent beam quality (M2<1.1) over a wide temperature range (10 to 40ºC). Due to its high efficiency, the full system typically consumes less than 25 W of electrical power.


515 nm is the 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 quality DPSS lasers to the fluorescence based bioanalytical industry to replace argon and krypton ion lasers: 491nm, 515nm, 561nm, 532nm and 473 nm lasers are currently available at output powers from 10 to 150mW.


The laser controller is available both in a CDRH version and as an ultra-compact remotely controllable OEM model. 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.
