Abstract
Disclosed is a laser wavelength conversion apparatus. The apparatus includes a focusing lens formed of a birefringent material and configured to have a same refractive index for an infrared laser beam and a green laser beam having different polarization directions and focus the infrared laser beam and the green laser beam without a chromatic aberration, and a sum frequency generator configured to combine the infrared laser beam and the green laser beam focused by the focusing lens to generate an ultraviolet laser beam. The apparatus of the present invention can solve a problem due to a chromatic aberration of the focusing lens, thereby improving a wavelength conversion efficiency and a beam quality.
