EKSMA OPTICS introduces new kit for third harmonic generation of Ti:sapphire laser. Kits consist of set of components required for efficient third harmonic generation of femtosecond Ti:Sapphire laser. The scheme of the efficient third harmonic generation is presented below:

Complete standard kit includes:
- Type 1 SHG BBO crystal with 6x6 mm aperture, P-coated @ 400-800 nm,
- Type 1 THG BBO crystal with 6x6 mm aperture, P-coated @ 400-800/266 nm,
- Calcite plate for group delay compensation, AR coated @ 800+400 nm,
- Zero order dual waveplate, optically contacted, AR coated @ 800+400 nm (code 465-4211)
- All above four components are mounted in to 1 inch ring holders for convenient handling.
The thickness of SHG BBO crystal, THG BBO crystal and group delay compensation plate is different in each kit and is optimal for certain pulse duration of fundamental harmonic to avoid harmonic pulses broadening.
