Abstract:

The first tunable CW laser action in both mode-locked and unmode-locked in both straight and ring cavity configurations has been demonstrated. The gain media were platelets of CdS, CdSe, InGaAsP, and HgCdTe. Pulse as short as 2.8 Psec and continous tunability between .5 micrometers and 2.5 micrometers has been achieved. Picosecond spectroscopy of bound excitons, using a synchronously operating streak camera and picosecond photoelectric emission from a Zirconium metal surface have been studied. The first experimental technique for compensating the pulse broading in single-mode optical fibers using the slow anomalous pulse propagation in the exciton-polariton resonance in a Direct-gap semiconductor has been demonstrated.
