EFFICIENT CONTINUOUS-WAVE BLUE-LIGHT GENERATION IN OPTICAL SUPERLATTICE LINBO3 BY DIRECT FREQUENCY-DOUBLING A 978 NM INGAAS DIODE

First-order quasiphase matched blue light generation in a LiNbO3 optic al superlattice was performed by direct frequency doubling of a contin uous wave 978-nm diode laser. 1.27 mW output power of blue light was o btained with an incidence power of 500 mW. The frequency conversion ef ficiency is 0.25%. (C) 1996 American Institute of Physics.
