Novel Design of Gain Region in Very-short Pulse VECSELS for Growth without Excessive Formation of Dislocations

This technology is a design of the gain region in a vertical-external-cavity surface-emitting laser (VECSEL) that can achieve ultra-short laser pulses depending on the placement of quantum wells on the chip, which allows for adaptation across a large range of frequencies. To prevent strain defects from appearing while still satisfying the optical gain...

Nonequilibrium High Peak and Average Power Pulsed Femtosecond Semiconductor Disk Laser

Researchers at the University of Arizona have developed a semiconductor disk laser that is engineered and fabricated to have sub wavelength spaced quantum wells to efficiently use all carriers available for lasing. The technology includes semiconductor saturable absorber mirrors (SESAMs). With the compact spaced quantum wells and absorber mirrors one...
