CW single-frequency ring Dye laser DYE-SF-077 -
Frequency-stabilized CW single-frequency ring Dye laser, model DYE-SF-077, is a further development of model DYE-SF-07. It now includes a system of frequency stabilization on the basis of a thermo-stabilized interferometer and a fast electronic driver.
Laser DYE-SF-077 features exceptionally narrow generation line width, which amounts to less than 100 kHz. DYE-SF-077 sets new standard for generation line width of commercial lasers. Prior to this model, the narrowest line-width of commercial dye lasers was as broad as 500 kHz - 1 MHz. It is necessary to note that the 100-kHz line-width is achieved in DYE-SF-077 without the use of an acousto-optical modulator, which, as a rule, complicates the design and introduces additional losses. A specially designed ultra-fast PZT is used for efficient suppression of radiation frequency fluctuations in a broad frequency range
570-700 nm, output > 1.5 W (10 W pump), linewidth < 100 kHz rms, frequency drift < 30 MHz/hour, smooth scanning 6/20 GHz.
The DYE-SF-077 laser cavity has horizontal orientation, the optical mounts of the cavity elements are attached to a rigid base plate, which is further stabilized by a volumetric framework with three invar rods underneath. Additional passive stability of the position of cavity elements is provided by the vibration isolating design of the laser base.
Dye laser DYE-SF-077 is the first representative of the new generation of dye lasers that offer to the user virtually the same level of convenience and simplicity of operation as with a solid-state tunable laser. As a result we are able to offer an option of combined configuration of DYE-SF-077 with Ti:Sapphire laser.
Laser DYE-SF-077 may be equipped with a USB compatible interface to remotely scan the generation line of the laser and to perform multi-channel data acquisition. Laser DYE-SF-077 also may be shipped together with an atom cell and a system for reduction of long-term generation line drift. Besides, laser DYE-SF-077 in combination with highly-efficient resonant frequency doubler FD-SF-07 delivers several hundreds milliwatts of narrow-band UV radiation within the 285–350-nm range.
