报道了利用引上提拉法生长出非线性光学晶体铌酸钾锂,并用其实现了对准连续可调谐钛宝石激光倍频.在波长为890—952nm范围内,通过室温下非临界相位匹配,得到445—476nm的二次谐波.抽运光强为144—269mW,二次谐波强度为058—173mW,倍频效率可达065%.
It is reported that the nonlinear optical crystal potassium lithium niobate is grown by the Czochralski method and used to achieve the laser frequency doubling of the continuously tunable Ti: sapphire crystal.At the wavelength of 890-952 nm, the non-critical phase matching , Resulting in the second harmonic of 445-476nm, the pumping light intensity is 144-269mW, the second harmonic intensity is 058-173mW, and the frequency doubling efficiency can reach 065%.
