Femtokits for efficient third harmonic generation

19 Oct 2017

Femtokit is a set of optical components and nonlinear frequency conversion crystals carefully chosen for particular laser pulse duration to achieve the best efficiency of frequency tripling of femtosecond Ti:Sapphire lasers.

Harmonic crystals used in Femtokits are optimized for specific pulse spectrum width and duration. Optimization of thickness of harmonic crystals allows to avoid femtosecond pulse broadening in frequency conversion process. Femtokits also include special group delay compensation plates for the fine adjustment of the delay / compensation between fundamental and second harmonic pulses before entering the harmonic generation crystal.

Now all Femtokits optimized for 70-120 fs and 30-70 fs fundamental pulse durations are provided with technical passports. A passport contains a testing report of SHG and THG efficiencies measured for the particular Femtokit with a few-mJ 100 fs or 50 fs Ti:Sapphire lasers. Test data provided in the technical passport can be later used to optimize your experimental setup for the maximum THG results.
