F. Laurell, STABLE BLUE 2ND-HARMONIC GENERATION IN A KTP WAVE-GUIDE WITH A DIODE-LASER IN AN EXTERNAL-CAVITY, Electronics Letters, 29(18), 1993, pp. 1629-1630
Stable second-harmonic generation from a diode laser, using a quasi-ph
asematching KTP waveguide and a grating in an external cavity is descr
ibed. 1.35 mW of blue light was generated and the power fluctuation wa
s less than 0.3%.
