Cobra-Stretch Tuneable Dye Laser

Cobra-Stretch Tuneable Dye Laser

With the Cobra Stretch, Sirah offer a two stage dye laser with space for an additional amplifier or frequency conversion unit (FCU). Absolute accuracy is < 30pm

An extension of the Cobra, the Cobra-Stretch adds a main amplifier or a frequency conversion unit (FCU). Either way, it includes preamplification of the resonator.

Mounting the FCU inside the laser housing guarantees excellent long term stability with reduced sensitivity to environmental influences. It is also possible to fix an optical parametric oscillator (OPO) inside the dye laser and use the dye laser as a narrow linewidth seed source.

Sirah also offer the PrecisionScan three stage dye laser and the Credo dye laser which is optimised for use with high repetition diode pumped solid state (DPSS) laser systems.
