| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a small, lightweight semiconductor laser device having a simple structure, capable of easily obtaining a high conversion efficiency and highly efficiently outputting short wavelength laser light of high power. SOLUTION: One end face 11 of a laser diode chip 10 is made into a total reflection surface and the other end face 12 into a non-reflective surface. An optical oscillator is formed by the one end face 11 and a wavelength selective mirror 15, a nonlinear optical crystal 14 is arranged within the oscillator for wavelength conversion, and then only light subjected to wavelength conversion is allowed to pass through the wavelength selective mirror 15 for output to the outside.
