请教-双BBO晶体OPO的相位补偿问题.

光电小猫 · 发表于 2009-10-7 10:04:04

有个导师在做两块BBO晶体OPO的相位补偿,但在晶体方面有一些疑问,麻烦各位大侠指点一二.多谢.

For Type II BBO with two 'e' waves, the situation is more complicated, since the sign of the nonlinear coefficient cannot be changed by rotation.  The sign of the nonlinear coefficient does alternate in Phi steps of 60°, so I can get two crystals to work properly together if one is cut at, for instance, Phi = 30° and the second is cut at Phi = 90° or 210°
  Can you cut two crystals with the Phi angle specified like this?  This is critical for my application!  I can send you a copy of a paper that explains this in great detail, if you like.
  Maybe I need these 2 BBO crystals as below:
1.)  Type II.  Theta = 37.2°, Phi = 30°,
2.)  Type II.  Theta = 37.2°, Phi = 90° or 210°,

两快BBO组合提高激光效率和光束质量，坛子里林老师能做哦
