Abstract.
Second-harmonic generation was z-cut observed Gd1-xYxCa4O(BO3)3 (Gd1-xYxCOB) and the dependence of the phase-matching wavelength on the mixing ratio x has been investigated. The dependence on both temperature and angle tuning was examined as well. We found the suitable composition for noncritical frequency doubling at 930 nm, which is the lasing wavelength of Nd:YAlO3 on the 4F3/2?4I9/2 transition.
