Optically-Pumped Semicoductor Disk Lasers with Intracavity Second-Harmonic Generation
نویسنده
چکیده
In this contribution, we present experimental results of our research on frequency-doubled semiconductor lasers emitting in the visible spectral range. These lasers include a laserdiode pumped semiconductor laser chip in an extended resonator configuration with a critically phase-matched lithium triborate crystal. The use of a single-plate Lyot filter within the cavity leads to single-peak emission with a bandwith of 1 nm at a 20 dB cliplevel. The achieved second-harmonic power emission of 407mW at a wavelength of 485 nm is still limited by the incident pump power.

We experimentally observe an intriguing phenomenon of complex spatio-temporal dynamics in a commercial optically pumped semiconductor laser with intracavity second harmonic generation. We numerically verify that the experimental results come from the total mode locking of transverse electromagnetic modes (TEM00) and higher-order modes with significant astigmatism.
