Second harmonic generators (SHG) are used for doubling of optical frequency for a wide range of input wavelengths produced by various ultrafast laser sources. The sources may be titanium-sapphire femtosecond lasers (Ti:S, 700-1000 nm), various ultrafast solid-state and fiber lasers around 1030-1064 nm region, chromium-forsterite oscillators (Cr:F, 1230-1270 nm), as well as other ultra-short pulse sources including parametric light conversion systems. The principle of operation is based on second harmonic generation in a non-linear crystal with phase-matching technique. The units provide stable output radiation with good beam quality and little pulse broadening in fs scale.
The models are subdivided into two main branches: the ASG-O-W for usage with ultrafast oscillators (multi-MHz rep. rates with nJ-level output) and the ASG-A-W with increased input aperture and modified layout for usage with amplifier systems (single-shot to several MHz, uJ- and mJ-level output). The "W" in the model name takes on the exact central wavelength value for a certain model, e.g. the ASG-O-800 (i.e. designed for an oscillator with ~800 nm output).
