PURPOSE:To provide a small size and high power light source which can output a short wavelength and short duration pulse by outputting a sum frequency light as a short wavelength and short duration pulse light beam. CONSTITUTION:The title pulse light source comprises a short pulse light source 1 and an energy injection light source 2. The light emission timings thereof are controlled to be synchronized by a timing period means 3. The short pulse beam from the short pulse light source 1 and the excited pulse beam from the energy injection light source 2 are coupled with a light coupling means 4 and are incident on a sum frequency light generating means 5. Letting the wavelength of the short pulse beam be lambdas, and the wavelength of excited pulse beam be lambdap, the wavelength lambdao of the sum frequency light from the sum frequency light generating means 5 is expressed as follow: 1/lambdao=1/lambdas+ 1/lambdap. Only the sum frequency light of the wavelength lambda0 is branched by a light ranching means 6 and is then outputted to external circuits as an output pulse, that is, short wavelength and short pulse light beam. |
