Sirah Lasertechnik’s WaveTrain 2 Series external cavity frequency doublers for cw lasers are powerful tools for efficient and stable second harmonic (WaveTrain 2) or fourth harmonic (WaveTrain 2 FHG) generation of single-frequency continuous wave lasers like the Matisse Series.

WaveTrain 2 Systems are based on a low-loss, ultra-compact enhancement cavity using a patented triangle-shaped ring resonator. A temperature stabilized nonlinear crystal generates the second harmonic of the enhanced fundamental radiation with very high efficiency of up to more than 35%. A Pound-Drever-Hall locking scheme in combination with an auto-relock stabilizes the length of the resonator cavity for ultra-stable second harmonic generation and widest automated tunability. The phase-matching angle of the nonlinear crystal is manually tunable over more than 50 nm.

The WaveTrain 2 Series provides highest flexibility for various single-frequency lasers. Two pre-mounted optics sets for quick and easy exchange cover the visible (VIS) to the near infrared (NIR) wavelength region. Various wavelengths are accessible by exchange of the pre-mounted crystal or by phase-matching angle tuning.

WaveTrain 2 systems provide space for integrating various mode-matching optics within the device’s housing. The sealed resonator block prevents contamination of the optics and allows easy flushing of the cavity with purified air or Nitrogen. The “Closed Loop Purge Unit” (CLPU) can be used as an option to purify the air inside the WaveTrain 2 system over years of operation.
