Laser characteristics of YVO4 crystal and its difference from yttrium aluminum garnet

YVO4 chip is a newly developed multi diffractive light energy crystal, which has outstanding light transmittance in the wide spectrum area of visible and near-infrared spectrometer. VO4 chip has its own properties, and has been quickly selected as a new birefringent optical material, which has been widely used in the photoelectric aquaculture industry. YVO4 wafer and rutile crystal recombination can also obtain satisfactory temperature compensation, and significantly improve the environmental stability of optical fiber communication devices

YVO4 chip ion beam properties and compared with yttrium aluminum garnet, YVO4 has higher transmittance to pump light and wider stimulated emission profile, which can achieve a good memory overclocking conversion rate. At present, YVO4 laser has been widely applied in different fields, such as equipment, material handling, clinical inspection, pulsed light printing, data storage, etc

compared with yttrium aluminum garnet, YVO4 has the advantages of wider absorption bandwidth and 5 times higher absorption efficiency than yttrium aluminum garnet. In addition, it reaches the valley absorption wavelength around 809 nm, which can fully meet the standard of high-power semiconductor lasers at this stage. This allows us to reasonably use smaller crystals to create smaller lasers. YVO4 has a large stimulated emission profile at 1063 nm and 1341 nm. The uninterrupted output power of yvo41343nm wave is higher than that of yttrium aluminum garnet, which makes it easier to maintain a strong single line excitation at both wavelengths of YVO4 laser. YVO4 is a uniaxial unit cell, which only emits linearly polarized light, so it can prevent the formation of multiple diffraction interference during overclocking conversion. Yttrium aluminum garnet is a high integrity dimensional crystal chip, and has no properties for the time being

advantages and disadvantages of YVO4 compared with yttrium aluminum garnet: the bandwidth and hardware configuration of the pump laser before and after 809nm is about 5 times that of yttrium aluminum garnet. The stimulated emission cross section at 1063 nm is three times that of yttrium aluminum garnet. YVO4 has low optical wear threshold and high tangent slope resistivity. It is a biaxial wafer and derived as linear polarization
