WAVELENGTH CONVERSION CRYSTAL AND WAVELENGTH CONVERSION LASER DEVICE |
摘要 |
A wavelength conversion crystal including: a single nonlinear optical crystal which satisfies both of a first phase-matching condition and a second phase-matching condition, the first phase-matching condition being required for first wavelength conversion to convert a fundamental wave having a wavelength of 1064 nm into a second harmonic having a wavelength of 532 nm, and the second phase-matching condition being required for second wavelength conversion to convert the light having a wavelength of 532 nm into a fourth harmonic having a wavelength of 266 nm; and a first reflective face and a second reflective face for reflecting the light having a wavelength of 532 nm generated by the first wavelength conversion to supply it to the second wavelength conversion. This approach can efficiently generate a third or higher-order harmonic with a reliable and simple configuration. |
