摘要:
The present invention belongs to the field of optoectronics. The main content of the present invention is to determine the optimum cut-orientations of ReCOB crystal frequency-doubling devices. For an example, the cut-angles of the YCOB crystal for 1064 nm are &thgr;1=(65.9±5.0)°, &phgr;1=(36.9±5.0)° or &thgr;2=(66.3±5)°, &phgr;2=(143.5±5)°. The present invention has solved the problem of low frequency-doubling conversion efficiency in the prior technique. The frequency-doubling technique of the present invention has advantages of high frequency-doubling conversion efficiency and low energy dissipation, and is useful for the application of the ReCOB crystal.
摘要:
This invention is a kind of electrooptic Q-switch element made of a single crystal and belongs to the application of crystal in electrooptic technology field. The invention consists of electrooptic Q-switch which is made of La3Ga5SiO14 or Nd:La3Ga5SiO14 or the other related crystal materials such as La3Ga5-xAlxSiO14, Sr3Ga2Ge4SiO14, Na2CaGe6O14, Ca3Ga2Ge4O14, La3Ga5.5Nb0.5O14 and La3Ga5.5Ta0.5O14 with the common shape or a specific shape containing Brewster angle as shown in figure. This kind of electrooptic Q-switch can be used in YAG laser and other laser. It overcomes the shortages of the commercial Q-switches, such as the high, un-adjustable, low stable half-wave voltage and great half-wave voltage variation with temperature. The advantage of this kind of electrooptic Q-switch is its low, adjustable, high stable half-wave voltage.
