Nd:YAG Crystal
Nd:YAG (Neodimium Doped Yttrium Aluminum Garnet) has been and continue to be the most widely used laser crystal for solid-state lasers. Good fluorescence lifetime (twice more than that of Nd:YVO4) and thermal conductivity, as well as robust nature, make Nd:YAG crystal very suitable for high-power continuous wave, high-energy Q-switched and single mode operations. -
Bonded Crystal
Diffusion bonded crystal consists of two, three or more parts of crystals with different dopants or same dopant with different doping levels. This material is commonly made by bonding one laser crystal with one or two undoped crystals by precise optical contact and further processing under high temperature. This innovative design substantially reduces thermal lens effect of the laser crystals, thus make it possible fora compact laser to have enough power. -
LASER WINDOWS
Optical windows are made by optically flat, transparent optical material that allow light into an instrument. Windows have high optical transmission with little distortion of the transmitted signal, but can not change the magnification of the system. Windows are widely used in various optical devices such as spectroscopic equipment, optoelectronics, microwave technology, diffractive optics, etc. -
WAVEPLATE
A waveplate, also called a phase retarder, is an optical device that changes the polarization state of light by generating an optical path difference (or phase difference) between two mutually orthogonal polarization components. When the incident light passes through wave plates with different types of parameter, the exit light is different, which may be linearly polarized light, elliptically polarized light, circularly polarized light, etc. At any particular wavelength, the phase difference is determined by the thickness of the waveplate. -
THIN FILM POLARIZER
Thin film polarizers are made from composed materials which include a polarizing film, an inner protective film, a pressure-sensitive adhesive layer, and an outer protective film. Polarizer is used to change un-polarized beam into linear polarized beam. When the light passes through the polarizer, one of the orthogonal polarization components is strongly absorbed by the polarizer and the other component is weakly absorbed, thus natural light is converted into linearly polarized light.
