Kerr-lens mode locking without dispersion compensation
- Max Born Institut fuer Nichtlineare Optik und Kurzzeitspektroskopie, D-12489 Berlin (Germany)
We propose and theoretically investigate a novel operating regime of femtosecond Kerr-lens mode-locked solid-state lasers that avoids group-velocity dispersion compensation by use of a nonresonant semiconductor plate in the focused resonator section that provides an overall negative nonlinear refractive index per round trip. The saturable loss of the laser resonator with an effective self-defocusing nonlinearity is derived from a generalized {ital ABCD} matrix formalism, and the correspondingly calculated steady-state pulse parameters show that a Kerr-lens mode-locked laser with an overall negative nonlinear refractive index generates stable femtosecond pulses without any dispersion compensation. {copyright} {ital 1996 Optical Society of America.}
