QUADRATIC NONLINEARITY-BASED HIGH-ENERGY PULSE COMPRESSOR FOR GENERATING FEW-CYCLE PULSES |
摘要 |
A pulse compressor for compressing many-cycle femtosecond-duration high-energy pulses to near-single-cycle durations uses a single quadratic nonlinear crystal. A pulsed laser beam is controlled and its passage is aligned through the quadratic nonlinear crystal such that the detrimental effects of group-velocity mismatch are avoided, while still allowing enough nonlinear phase accumulation for compression to near-single-cycle pulse durations. To do so, the perturbation to nonlinear Schrödinger-type soliton compression due to group-velocity mismatch is minimized which requires that the soliton order must not exceed an optimal value set by the amount of group-velocity mismatch.
