Abstract
In order to generate efficiently a deep ultraviolet laser beam having a wavelength in a deep ultraviolet region and to make the generated laser beam to be high output, it is arranged in such that a laser beam having about 227 nm wavelength is generated by sum-frequency mixing of fourth harmonic of the laser beams obtained by amplifying semiconductor laser beams having 1064.0 to 1065.0 nm wavelengths by means of an optical fiber amplifier, and the laser beams obtained by amplifying semiconductor laser beams having 1557.0 to 1571.0 nm wavelengths by means of another optical fiber amplifier; and further laser beams having 198.4 to 198.7 nm wavelengths are generated by sum-frequency mixing of the above sum-frequency mixed laser beam and the above-described semiconductor laser beams having 1557.0 to 1571.0 nm wavelengths.
