Nd:YAG

Nd:YAG crystal is the most widely used solid-state material nowadays. We can now supply high-quality Nd:YAG rods with high optical homogeneity and durability, consistent performance, and high processing accuracy. In order to meet the requirements of our customers, an improved quality assurance procedure has been implemented during the crystal growing and fabrication process on site at our supplier.

Nd:YVO4

Nd:YVO4 is one of the most efficient laser crystals that exist for diode-pumped solid-state lasers. The crystal has a large stimulated emission cross-section, high absorption coefficient, wide absorption bandwidth, and high laser-induced damage threshold, as well as good physical, optical, and mechanical properties. This makes Nd:YVO4 an excellent crystal for high-output cost-effective lasers that are subject to requirements for good stability. Nd:YVO4 can produce powerful and stable IR, green, and blue surface-emitting laser output.

Nd:YVO4 demonstrates its advantages to other laser crystals, in particular, for applications that require a more compact design and SLM (Single Longitudinal Mode). The crystal is perfect for laser tools for micromachining and material processing, spectroscopy, wafer inspection, light shows, medical diagnostics, laser printing, etc.

We can offer Nd:YVO4 crystals with a surface treatment for minimum optical loss with a bulk of up to f30×70 mm3 and a size of up to f20×20 mm3 at very competitive prices.

KTP

Advantages of KTP:
− High nonlinear optical coefficient,
− wide angular bandwidth and small walk-off angle,
− Broad temperature and spectral bandwidth,
− High electro-optic coefficient and low dielectric constant,
− Non-hydroscopic, chemically and mechanically stable.

Applications:
− Frequency doubling (SHG) of Nd-doped lasers for green/red output,
− Frequency mixing (SFM) of Nd lasers and diode lasers for blue output,
− Parametric sources (OPG, OPA and OPO) for 600 to 4,500 nm tunable output,
− E-O modulators, optical switches and directional couplers,
− Optical waveguides for integrated NLO and E-O devices.

Cr:YAG

Cr:YAG Q-switching is a technology for the generation of short laser pulses with a very high output. CR:Yag uses passive Q-switching which is generally preferred for its simplicity of manufacturing and use, cost-effectiveness, as well as size- and weight-efficiency. CR4 +: YAG is an excellent crystal for passive Q-switched lamp- or diode-pumped lasers, for example, Nd:YAG, Nd:YLF, Yb:YAG or Nd and Yb-doped lasers with a wavelength of between 1.0 and 1.2 mm.
Due to its chemical stability, durability, UV resistance, good thermal conductivity, high damage threshold (> 500 MW/cm2), and simple operation, in future this technology will replace traditional switching materials such as, for example, LiF, organic dye and solid-state colour centres.
