Abstract
A 25 mW continuous-wave blue laser is demonstrated by noncritical type I phase-matched sum-frequency mixing of a master-oscillator power-amplifier InGaAs laser diode and an AlGaAs laser diode in a potassium niobate (KNbO3) crystal. The blue laser is continuously tunable over the wavelength range from 431 to 438 nm.Keywords
