摘要： A laser assembly generates continuous (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.

摘要： A method and system for beam shaping employing a non-collinear quasi phase-matched interaction in a crystal whose nonlinear coefficient was encoded by a computer generated hologram is provided herein. The same axis is used for both satisfying the phase-matching requirements and encoding the holographic information. This allows one-dimensional beam shaping using a very simple to fabricate nonlinear crystal pattern and two-dimensional beam shaping with high conversion efficiency. Both are demonstrated by converting a fundamental Gaussian beam into Hermite-Gaussian and Laguerre-Gaussian beams at the second harmonic in KTiOPO4 and stoichiometric lithium tantalate. The suggested scheme enables broad wavelength tuning by simply tilting the crystal.

摘要： A tunable coherent radiation source comprises a pump laser which outputs a pump beam and a non-linear optical medium having a tuning pattern to provide tuning across a wavelength range. A translation system is arranged such that the pump beam is translated across the tuning pattern. The scanning pattern is formed such that translation of the pump beam across the tuning pattern provides one or more discontinuities in tuning across the wavelength range. A spectroscopic system and a hyperspectral imaging system comprising such a tunable coherent radiation source are described, as is a non-linear optical medium adapted for use in such a source. A method of providing coherent radiation tuned over a wavelength range is also described.

摘要： A light source emits first incident light to a first polarization-reversed structure. The first polarization-reversed structure then converts the wavelength of the first incident light to emit a higher harmonic wave. A fiber coupler divides the higher harmonic wave output from the first polarization-reversed structure into output light emitted from the light source device and feedback light. The feedback light enters a second polarization-reversed structure. The second polarization-reversed structure then converts the wavelength of the feedback light to emit second incident light. The second incident light has the same wavelength as the first incident light. The second incident light enters a first wavelength converter.
