AI Article Synopsis
- - A diode-pumped Nd:glass laser oscillator was developed that does not use prisms and features mode-locking through a semiconductor saturable absorber.
- - The laser's stability against self-Q-switching was achieved by using a phase-mismatched second harmonic crystal.
- - The system produced incredibly short pulses, reaching up to 520 femtoseconds (fs), utilizing negative-index cascaded second-order nonlinearity for soliton shaping with normal intracavity dispersion.
Article Abstract
A diode-pumped, prismless Nd:glass laser oscillator, mode-locked by a semiconductor saturable absorber, was stabilized against self-Q-switching by using a phase-mismatched second harmonic crystal. Furthermore, negative-index cascaded second-order nonlinearity provided the soliton shaping mechanism with normal intracavity dispersion. Nearly Fourier-limited pulses as short as 520 fs were obtained.
