SEMICONDUCTOR LASER DEVICE USING AN EXTERNAL RESONATOR, CAPABLE OF MANUFACTURING GREEN LIGHT SOURCE BY FORMING A LASER DIODE FOR PUMPING USING A FABRY-PEROT TYPE LAYER DIODE
SEMICONDUCTOR LASER DEVICE USING AN EXTERNAL RESONATOR, CAPABLE OF MANUFACTURING GREEN LIGHT SOURCE BY FORMING A LASER DIODE FOR PUMPING USING A FABRY-PEROT TYPE LAYER DIODE
PURPOSE: A semiconductor laser device using an external resonator is provided to easily arrange a laser diode chip, a lens, light of a reflection mirror by forming the external resonator into double folder shape.;CONSTITUTION: The axis of laser light emitted from a semiconductor laser diode chip(100) is bent at least twice. The bent laser light is emitted to the outside. An external resonator includes a non-linear optical material(400) which changes the wavelength of the laser light from the laser diode chip. The non-linear optical material includes either of potassium titanyl phosphate or lithium niobate.;COPYRIGHT KIPO 2011
