LDRD Project progress report: Broadly tunable, solid-state coherent light sources

PDF Version Also Available for Download.

Description

Our program of nanosecond optical parametric oscillator (OPO) development has concentrated on improving the spectral purity and tunability as well as the beam quality of OPO`s and other tunable sources based on frequency mixing in nonlinear crystals. To facilitate quick evaluation of new OPO and frequency-mixing configurations and to provide insight to OPO operation, we developed a computer model of seeded OPO operation that includes pump depletion, birefringent walkoff, diffraction, temporal and spatial beam profiles, and cavity optics. It predicts conversion efficiency, beam quality, spectra, and time behavior. Our model development was complemented by laboratory OPO studies that served to ... continued below

Description

Our program of nanosecond optical parametric oscillator (OPO) development has concentrated on improving the spectral purity and tunability as well as the beam quality of OPO`s and other tunable sources based on frequency mixing in nonlinear crystals. To facilitate quick evaluation of new OPO and frequency-mixing configurations and to provide insight to OPO operation, we developed a computer model of seeded OPO operation that includes pump depletion, birefringent walkoff, diffraction, temporal and spatial beam profiles, and cavity optics. It predicts conversion efficiency, beam quality, spectra, and time behavior. Our model development was complemented by laboratory OPO studies that served to validate the model and also to highlight the practical problems associated with limitations of optical coating and nonlinear crystal growth technologies. We present here a set of papers that compare model calculation and laboratory characterization of a seeded, nanosecond OPO, that apply the model to illustrate distortions of specta and beam quality in frequency mixing, and that point out the peculiarities of two-crystal frequency mixing.
