Nd:YVO4 crystal is an excellent laser for making the diode-pumped solid lasers. The primary and most significant advantages of Nd:YVO4 are high absorption coefficient, significantly stimulated emission cross-section and wide absorption band. The absorption peak is about 808 nm. Because of these advantages, tiny crystals can be used to make smaller laser devices. Another feature of Nd:YVO4 crystal is this uniaxial, which makes it emit linearly polarized lights. It is combined with frequency doubling crystals to enable an all-solid-state laser with green, blue, and red wavelengths.

Dear Sirs, could you provide the laser crystals under our request according to the specification below:
It must be three crystals glued together with a coating: the 1st – quartz crystal (SiO2), the 2nd – Neodymium Doped Yttrium Vanadate crystal (Nd:YVO4), and the 3rd – KTP – Potassium Titanil Phosphate crystal (KTiOPO4) . The length of the 1st (quartz crystal) is 0.6 +/-0.1 mm, the length of the 2nd (Nd:YVO4) crystal is 0.7 +/-0.1 mm, and the length of the 3rd KTP crystal is 1.7 +/- 0.1 mm. The required Nd:Doping Level is 2.0 atm %. The common length of this crystal must be 3+/- 0.1 mm, the diameter should be as small as you can do it, i.e. 1 or 2mm. It will be a sample to understand how it will fit to our purpose. For another quality requirements please see specification below:

Hello, I represent the company “laboratory of optical crystals” LLC. We need optical elements. Interested in the possibility of manufacturing and delivery price.
Plane-parallel plates for the LIO filter made of unalloyed YVO4 (radiation tuning range 3-5 microns).
the diameter of the plates d= 40 mm.
Material-YVO4 plate thickness: 12 mm, 6mm, 3mm, 1, 5 mm, 0.75 mm
The plates must be cut parallel to the optical axis C (to change the birefringence depending on the rotation of the plate relative to the normal to the surface of one of the working sides).
Sincerely, leading optician of LLC “laboratory of optical crystals” Yudin Nikolay Nikolaevich.
