DYE-SF-07

Tunable single frequency dye laser

Wavelength            520-700 nm
Output power         > 1.5 W (10 W pump power)
Scanning range      6 / 20 / 40 GHz / 80 GHz
Linewidth                < 10 MHz/s (1MHz/0,1s) rms
Dye laser DYE-SF-07 is the first representative of the new contemporary generation of dye lasers that offer to the user virtually the same level of convenience and simplicity of operation as with a solid-state tuneable laser. Similarity of this laser to a solid-state one is emphasized by the fact that DYE-SF-077 can be optionally shipped in the combined configuration which allows its operation as a Ti:Sapphire laser.
 
CW single-frequency ring Dye laser, model DYE-SF-07, is a powerful solution of a source of tuneable radiation in the range of 520-700 nm for research in cold atoms and ultra-high resolution spectroscopy.
Dye laser construction resonator cavity in operation
The output power of the laser exceeds 1.5 W when pumped with 10 W at either 532/515-nm wavelength or all blue-green lines of Ar laser (488 nm pump laser is needed to achieve 520 - 550 nm range).
The horizontal orientation of the resonator plane allows compact arrangement of the cavity elements on a rigid and massive vibro-isolated base of DYE-SF-07, which ensures high stability of the generation parameters of Dye laser.

Active frequency stabilisation performed through an external thermo-stabilised cavity is available in model DYE-SF-077; it provides short-time linewidth less than 100 kHz/s rms and line stability down to 4MHz/h.
Dye laser resonator cavity design layout beam path
The standard spectral range of the laser of 520-700 nm can be extended into the 260-350 nm range by using the efficient resonant external frequency doubler FD-SF-07. Output power up to 300 mW can be reached if pumped by 1,5W @ fundamental wavelength.
