Optical parametric oscillator wideband frequency comb generator

摘要: One or more optical parametric oscillators are arrayed selectively singly, serially, and/or in parallel, and each oscillator is responsive to an input pump beam having a fractional stability produce output signal idler beams stabilities that correspond better than the of such way sum frequencies constrained be equal frequency thereof. beat detectors selected one reference already known provide detection signals linewidths corresponding difference between beams. The constraints completely determine absolute several thereby enabling different configurations ultrahigh resolution calibration recalibration, broadband ultr This invention was made with government support under Grant Number MDA 904-90-C-5070 awarded by Maryland Procurement Office, Contact DAAL03-90-G-0128 Department Army 60NANB0D1052 Commerce. has certain rights invention.
