The Yb:CaF2 crystal, also known as Ytterbium-doped calcium fluoride, is a unique laser-active material that is grown using the Czochralski technique. This material is particularly useful in generating high-power, ultra-short pulses. Among the family of ytterbium-doped laser crystals, Yb:CaF2 stands out due to its exceptionally long fluorescence lifetime of approximately 2.2 milliseconds.

Yb:CALGO crystal is a novel laser active material used to generate high energy ultrashort pulses with less than one hundred femtoseconds (< 100 fs). From ytterbium doped laser crystals family Yb:CALGO crystal is used to generate the shortest pulses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is a remarkable material that plays an important role in laser technology. Its primary function is to generate ultrashort pulses of light, spanning just a few hundred femtoseconds. By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW due to the similar sizes of these chemical elements up to 100% of Yb-doping could be achieved.

Yb:YAG crystal, also known as Ytterbium-doped yttrium aluminum garnet is used in production of short and ultrashort pulse lasers. Wide absorption bandwidth centered at 940 nm makes it well suited to be pumped with laser diodes. High thermal conductivity of Yb:YAG crystal makes it a perfect gain material for high power lasers.

Ho:YAG crystal, also known as Holmium-doped yttrium aluminum garnet is a reliable material for direct Ho³⁺ excitation, operating in the 2.1 µm spectral range. It’s used in various applications, including atmospheric remote sensing and high harmonic generation. The low quantum defect of Ho:YAG, combined with the excellent thermo-mechanical properties of YAG, results in a small heat load and potential for scaling to high output power. Ho:YAG crystals available from stock.
