• intracavity frequency conversion

In the paper, a new way of intracavity frequency-tripled all-solid-state laser to generate continuous wave blue coherent radiation is firstly demonstrated. High-efficiency of continuous wave third harmonic generation using the approach of double-resonance at fundamental frequency and second harmonic is developed by insertion of one wedge prism for the phase control. The maximum output power at the wavelength of 447 run, which was generated with two long LiB3O4 crystals by noncritical phase matching, is about 1. 15 W with a beam quality factor of M-2 of 1.05. From the experimental results, the generation of continuous wave blue light using this way with higher conversion efficiency can be achieved.
