Production of Laser and Optical Elements

Yttrium aluminum garnet crystals with erbium are crystals, suitable for generating almost any wavelength output radiation. Highly doped Er:YAG crystals contain about 50% of the yttrium atoms replaced by erbium atoms, thanks to what you can get radiation with a wavelength of 2940 nm. Radiation with with such parameters is able to absorb water, and therefore it is used in dentistry, cosmetology and ophthalmology.

Crystals of yttrium-aluminum garnet with ytterbium have many unique characteristics: high quantum efficiency, lack of absorption in the excited state and losses with increasing frequency, for a long time upper laser level radiation, large absorption width. They feature unsurpassed optical, thermal and mechanical properties.

Crystal of yttrium-aluminum garnet doped with neodymium (Nd:Y3Al5O12 or Nd:YAG) continues to be considered the best of rare earth materials. Lasers based on this crystal characterized by a four-level energy scheme, with which achieves a low threshold pulse and a continuous radiation.

YAG(Ce) or Ce:YAG is a non-hygroscopic, chemically inert inorganic scintillator. Wavelength maximum emission at 560 nm is in good agreement with the sensitivity of the CCD. Ce:yag is enough fast scintillator with a relative light output of 21% NaI (Tl). C:YAG scintillators are used in SEM, electronic imaging, beta-ray and X-ray counters and imaging. He possesses excellent thermal and mechanical characteristics, making it suitable for ultra-thin screen <0.005 mm. Ce: YAG crystals have a high threshold for electrons or ions high energy, which makes it suitable for high electric current operation.

The mirror reflector is made of quartz, on the outer surface of which the reflective layer is made of silver and covered with a protective galvanic coating.
