We offer fs-Kits for Type I third harmonic generation (THG) of Ti:sapphire lasers. Each THG kit consists of the following four crystals,
(1) A BBO crystal for Type I second harmonic generation (SHG),
(2) A BBO Crystal for Type I sum frequency mixing to generate the THG,
(3) A calcite time delay compensator to be placed after the SHG crystal to optimize the temporal overlap of the pulses in the THG crystal,
(4) A dual waveplate to turn the orthogonal polarizations from the SHG crystal into parallel polarizations for Type I THG. The waveplate is ultrathin ~ 45 μm to maximize the bandwidth and to minimize the dispersion.
The configuration of the crystals for THG is shown under the "Tech Info" tab.
Standard BBO crystal apertures are 5, 10, 12 mm. 15 mm is available upon request. Thicknesses of the crystals are designed to maximize the THG conversion efficiency without the undesired pulse broadening. All crystals are mounted in an OD 1" anodized aluminum holder and can be further mounted into a conventional mirror mount for 1" optics for angular tuning. Mirror mounts are not included in the THG kits, but are available upon request at additional costs or can be purchased separately from a third party (Ref. "Tech Info" tab).
The selection of the THG kit is highly dependent on the fundamental laser. Please send us an inquiry with your laser parameters, i.e. the central wavelength, pulse energy, repetition rate, and the beam size if you need an assistance.
Type II THG kits are also available. There is no need of the dual waveplate for Type II THG.
