Abstract
We report on the frequency doubling of Q-switched Nd:YAG and Nd:YAlO3 laser s emitting at 946 and 930 nm, respectively (F-4(3/2) to I-4(9/2) transition ). The neodymium-doped laser host crystals were excited with a flashlamp-pu mped Cr:LiSAF laser operating in a free-running mode. Blue-light pulses wer e obtained at both 473 nm (9 mJ, 25 ns FWHM) and 465 nm (4.4 mJ, 35 ns FWHM ) by using a potassium niobate crystal as an extra-cavity frequency doubler . The second-harmonic generation conversion efficiencies reached 53% and 31 %, respectively.
