Femtosecond synchronously mode-locked vertical-external cavity surface-emitting laser.
The behavior of a room temperature synchronously mode-locked vertical-external cavity surface-emitting laser (VECSEL) operating at 980 nm is reported. The laser performance was found to be qualitatively the same for different pump pulse duration (3.6 ps and 70 fs). The pulse duration of the laser is limited by strong self-phase modulation to around 10-40 ps. By compressing the strongly chirped ...
متن کاملVertical cavity surface emitting terahertz laser.
Vertical cavity surface emitting terahertz lasers can be realized in conventional semiconductor microcavities with embedded quantum wells in the strong coupling regime. The cavity is to be pumped optically at half the frequency of the 2p exciton state. Once a threshold population of 2p excitons is achieved, a stimulated terahertz transition populates the lower exciton-polariton branch, and the ...
متن کاملDirect Measurement of Pump Intensity Distributions in an Optically Pumped Vertical-Cavity Surface-Emitting Laser
We have mapped the internal pump intensity distribution by monitoring the spontaneous emission intensity along the cleaved edge of an optically pumped vertical-cavity surface-emitting laser (VCSEL) using the high spatial resolution and shallow depth of field provided by near-field scanning optical microscopy (NSOM) [1]. The spontaneous emission of quantum wells placed throughout the distributed...
متن کاملOptically pumped GaN vertical cavity surface emitting laser with high index-contrast nanoporous distributed Bragg reflector.
Laser operation of a GaN vertical cavity surface emitting laser (VCSEL) is demonstrated under optical pumping with a nanoporous distributed Bragg reflector (DBR). High reflectivity, approaching 100%, is obtained due to the high index-contrast of the nanoporous DBR. The VCSEL system exhibits low threshold power density due to the formation of high Q-factor cavity, which shows the potential of na...
