Tunable laser radiation from UV to near IR

GWU-Lasertechnik develops and manufactures OPOs for scientific and industrial applications.

GWU introduced the first commercial BBO-OPO in 1989, and thus claims the broadest base of experience in these products.

An all new series of pulsed BBO-OPOs is introduced at Laser 2005.

The new product family comes in a broad range of configurations including an ultra-compact manually tuned instrument (Basiscan), a general purpose instrument (Versascan) with many options like manual or PC-based motorised tuning and a high-end model (Preciscan) that represents the ultimate in performance even in the edges of the tuning range.

Design goal of these systems were ease of operation, rugged design and modular configuration to cover most scientific and industrial applications for tunable solid-state laser systems.

Options include manual or motorised tuning, motorised crystal change (in Preciscan), continuous tuning over the whole wavelength range (Basiscan and Versascan), harmonic generation (doubling/mixing), and low divergence operation among others.

GWU, being independent from pump laser manufacturers, has designed these OPOs to be adaptable to most pulsed Nd:Yag lasers on the market including Innolas, Spectra-Physics, Quantel, Continuum, and Spectron.

So these OPOs are ideal complements for existing Nd:YAG lasers and of course perform well in all new installations, it says.

GWU has successfully integrated its OPOs into customised Integra systems together with Nd:Yag lasers of various brands and with additional components such as wavemeters and harmonic generators.

So the whole tunable light source is contained in an easy to move compact box.

Some of these Integra systems are being operated in harsh environments and even outdoors.

Since the Laser Munich show in June 2005, GWU has introduced the improved version of optional OPO wavemeter model Lambdascan.
