Abstract

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.
