  • Harmonic Generators up to 210 nm

  • Output up to 150 mJ

  • Low divergence < 2 mrad

  • Compact footprint

  • The WT200 Series Optical Parametric Oscillator (OPO) is a high performance tunable laser source designed for applications requiring high pulse energy, efficient wavelength conversion, and reliable long term operation. Building on Wavelight’s expertise in advanced laser technologies, the WT200 provides a flexible and compact solution for generating tunable radiation in the visible and near infrared spectral regions.

    The advanced optical design of the WT200 enables high conversion efficiency at relatively low pump intensities, reducing thermal effects and minimizing maintenance requirements while ensuring stable long term performance. Optimized for operation with pump energies up to 350 mJ at a pump wavelength of 355 nm, the system provides efficient parametric conversion with pulse widths from 4 to 12 ns.

    The WT200 Series supports continuous wavelength extension into the UV region from 210 to 680 nm when combined with the WH300 external Second Harmonic Generator. The modular configuration allows easy integration with optimized WH Series pump lasers, while rigid alignment between the pump laser and OPO maintains system performance during transportation and operation.

    With PC control, compact footprint, and optional wavelength monitoring solutions using an integrated spectrometer or wavelength meter, the WT200 Series offers a versatile platform for advanced spectroscopy, nonlinear optics, and other demanding scientific applications.

  • Harmonic Generators

    To extend the tuning range into the UV spectrum, the WT220 and WT230 OPOs can be equipped with the WH300 external Second Harmonic Generator.

    When combined with the WT200, the system provides UV wavelength tuning from 210 nm to 420 nm.

    With the WT230, the tuning range covers 340 nm to 680 nm.

    PC Control

    For integration into automated systems, the OPO can be optionally equipped with PC controlled stepping motors. This configuration includes a dedicated controller and user friendly software for full remote operation.
