The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and also the higher-point out lifetime.
GWU delivers all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) with a wide a number of technical specs. Other than the perfectly-recognized elements, modern crystals with fantastic Qualities like Yb:CALGO can open up new horizons for demanding laser apps. It does not matter irrespective of whether particular person pieces for R & D purposes are expected or Expense-economical figures in small, medium or substantial batches with in-time delivery for that production line are essential: GWU’s dedicated provider really helps to find the greatest Main components to your software.
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
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。
Several laser crystal products have already been shown exactly where some saturable absorber substance is included for passive click here Q switching of the laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
It is clear that various programs cause really unique needs on laser acquire media. For that reason, a broad vary of various crystals are utilized, and building the ideal choice is essential for constructing lasers with ideal overall performance.
