The output of an ideally mode-locked laser, namely, one having equal phase angles of the modes, consists of a train of bandwidth-limited short pulses. The influence of deviations from equal phase angles on the laser output is investigated. Random distribut ...
Optically excited (Fa, In, As, P) film lasers at 1. 3 and 1. 5 mu m have been investigated. The lasers showed single-mode emission and a tuning range of up to 160 nm. The laser threshold P//t and the differential quantum efficiency eta //D have been invest ...
Photoluminescence intensity and emission wavelength of InAsP/InGaAsP and InGaAs/InGaAsP multi-quantum well (MQW) laser structures grown by chemical beam epitaxy (CBE) at 460 degrees C and V/III ratio of 2 are considerably affected by annealing at temperatu ...
Pump and Probe measurements with femtosecond pulses are performed on a Gain-Clamped Semiconductor Optical Amplifier (a special laser structure). The relaxation oscillations of the carriers density are observed directly in the time domain, Reasonable values ...
A simple energy-grained master equation was used to model data on the multiphoton dissocn. of CF2HCl as a function of laser fluence and Ar bath-gas pressure. Information on energy transfer from vibrationally excited CF2HCl was obtained from an anal. of the ...
When mixts. of O3 and mol. H2 were flashed in a laser cavity, stimulated ir emission at 3050-3410 cm-1 was detected, and the radiation was identified as the P1 transitions of the v = 3 -> 2, 2 -> 1, and 1 -> 0 fundamentals of the OH radical. Stimulated emi ...
