A phase-modulation interferometer for intense, ultrashort, near infrared laser pulses
S. Ganeshamandiram, M. Niebuhr, F. Richter +4
The investigation of coherent phenomena in strong-field processes requires interferometric measurement schemes with high selectivity to disentangle the complex nonlinear response o…
