The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the higher-point out lifetime.
GWU delivers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) with a wide a number of technical specs. Moreover the perfectly-founded elements, impressive crystals with fantastic Homes like Yb:CALGO can open new horizons for demanding laser purposes. Irrespective of regardless of whether specific pieces for R & D purposes are demanded or Charge-productive quantities in smaller, medium or huge batches with in-time shipping and delivery for the generation line are required: GWU’s committed services helps to locate the very best Main components on your software.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
Some laser crystal components have been demonstrated wherever some saturable absorber content is included for passive Q switching of a laser.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
It is apparent that distinct apps bring on really diverse necessities on laser obtain media. This is why, a wide array of various crystals are utilised, and building the appropriate preference is important website for setting up lasers with optimum efficiency.

The medium must have a high transparency (very low absorption and scattering) during the wavelength areas of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the caliber of the fabric, based on aspects of the fabrication approach.
With that concept, 1 isn't going to need a further saturable absorber crystal, in order that a single might make additional compact Q-switched laser setups with reduce inside parasitic losses. However, undesirable Uncomfortable side effects can also manifest, such as getting unwanted valence states on the included ions or Power transfers.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
