Abstract:
A laser assembly generates continuous wave (CW) laser output light in the range of approximately 181 nm to approximately 185 nm by generating fourth harmonic light from first fundamental CW light having a first fundamental wavelength between 1 μm and 1.1 μm, generating fifth harmonic light by mixing the fourth harmonic light with the first fundamental CW light, and then mixing the fifth harmonic light with second fundamental or signal CW light having a second wavelength between 1.26 μm and 1.82 μm. The fifth harmonic light is generated using an external cavity that circulates first fundamental CW light through a first nonlinear crystal, and by directing the fourth harmonic light through the first nonlinear crystal. The laser output light is generated using a second cavity that passes circulated second fundamental or signal CW light through a second nonlinear crystal, and directing the fifth harmonic light through the second nonlinear crystal.

Claim (Index 11):
A method of inspecting a sample, the method comprising:\n generating continuous wave (CW) laser output light having a wavelength in the range of approximately 181 nm to approximately 185 nm, wherein generating said CW laser output light includes:\n generating a first fundamental CW light having a first fundamental frequency with a corresponding first fundamental wavelength between about 1 \u03bcm and 1.1 \u03bcm; \n converting a first portion of the first fundamental CW light to a fourth harmonic light having a fourth harmonic frequency equal to four times the first fundamental frequency; \n generating a fifth harmonic light having a fifth harmonic frequency equal to five times the first fundamental frequency by mixing a second portion of the first fundamental CW light and the fourth harmonic light, wherein said mixing comprises circulating said second portion in a first cavity such that said circulated first fundamental CW light passes through a first nonlinear crystal that is also positioned to receive said fourth harmonic light; and \n mixing the fifth harmonic light with second CW light having a second frequency with a corresponding wavelength between 1.26 \u03bcm and 1.82 \u03bcm to generate said CW laser output light, wherein said mixing comprises circulating said second CW light in a second cavity such that said circulated second CW light passes through a second nonlinear crystal that is also positioned to receive said fifth harmonic light; \n directing the output laser light onto an article being inspected; and collecting an image information portion of said laser output light affected by the article being inspected, and directing the image information portion to one or more sensors, wherein at least one of the first and second nonlinear crystals comprises one of an annealed cesium lithium borate (CLBO) crystal, a hydrogen-treated CLBO crystal and a deuterium-treated CLBO crystal.
