Abstract: <P>PROBLEM TO BE SOLVED: To project laser light with stable output power.  <P>SOLUTION: Periods of a polarization reversal structure provided in a secondary harmonic generator should accurately be set according to the wavelength of a fundamental wave to obtain high conversion efficiency. A transmission type grating is disposed between the secondary harmonic generator and a light source to make light, which travels along an optical axis to be incident on a wavelength converting element, incident on the secondary harmonic generator at an incidence angle increasing with the wavelength by using diffracting operation of the transmission type grating. For example, an effective polarization reversal period on an optical path of light of wavelength λ2 at an incidence angle θ2 is d2 and an effective reversal period on an optical path of light of wavelength λ1 at an incidence angle θ1 is d1. Here, the effective polarization reversal periods at the respective wavelengths are so related that d1>d2 and a polarization reversal period can be set longer for light having a longer wavelength, so that a phase matching condition is met. Therefore, high conversion efficiency can be always obtained even when the wavelength varies.  <P>COPYRIGHT: (C)2008,JPO&INPIT
