摘要:
Self‐oscillations of V‐channeled substrate inner stripe (VSIS) lasers with index guiding and the influence of external feedback on low‐frequency noise generation are presented. The self‐oscillation is induced by means of shortening a cavity length of VSIS laser to 110 &mgr;m. VSIS lasers with self‐oscillation have the fundamental linewidth of 0.56 A˚ below 3 mW and are not sensitive to both phase and amplitude of the externally reflected light. Signal to noise ratio of short‐cavity VSIS laser at 1 MHz with a 10‐KHz bandwidth was 97 dB at 0.05% optical feedback.

摘要:
We report here the successful operation of a Beaulieu‐type TE‐CO2laser using equalizing inductances. An improvement of 50% or more in the efficiency was observed over resistance‐ballast system.

摘要:
A synchronously operated picosecond streak camera has been used in a direct time‐resolved study of luminescence and laser emission from a GaAs/(GaAl)As double heterostructure laser pumped by <90 ps, 514‐nm optical pulses from a mode‐locked Ar ion laser. Semiconductor laser pulse widths down to 20 ps were recorded and the dependence of the temporal characteristics of these pulses on average pump power was investigated.

摘要:
We report a factor of 65 compression of the 5.9‐ps [full width at half‐maximum (FWHM)] pulses from a mode‐locked dye laser by a two‐stage technique. In each stage the laser pulses were frequency broadened and linearly chirped by passage through a single‐mode optical fiber, and then compressed by traversal of a diffraction grating based dispersive delay line. The final compressed output pulses had pulse widths of 90 fs (FWHM), peak powers of more than five times that of the input pulses, and were continuously tunable over the 300‐A˚ range of the laser dye.

摘要:
Observation of anomalous longitudinal mode behavior from deep Zn‐diffused GaAs/GaAlAs lasers is reported. Single longitudinal mode operation is maintained without any mode hopping over a temperature range of more than 40 °C when the current is fixed. The spectrum, however, is quite sensitive to current changes.

摘要:
The use of polymer shells, filled with dichlorodifluoromethane in laser compression experiments is described. The absence of shell emission leads to chlorine spectra with little contaminating shell continuum emission. The low x‐ray opacity of polymer indicates that chlorine heliumlike emission could be detected even with compressed shell areal density of 0.1 gm cm−2.

摘要:
Effect of an active layer thickness on the lateral and longitudinal modes of the gain guiding laser with a tapered stripe structure has been studied. We observed broadening in the linewidth of each longitudinal mode as well as continuous emission spectra for the tapered stripe lasers with the thicker active layer of more than 0.1 &mgr;m. From the measurement of longitudinal as well as lateral modes, it is concluded that hole burning effect is enhanced in the thicker active layer as was pointed out by Copeland. The experimental results observed for the tapered stripe lasers are inherent to gain guiding lasers with a stripe geometry structure.

摘要:
It is well known that a ZnO‐on‐Si structure supports two distinct surface waves, called the Rayleigh and the Sezawa modes, if the ZnO layer is sufficiently thick. Herein we report a unique surface wave resonator that operates by efficiently converting between the two modes at the resonant frequency. The mode conversion resonator promises enhanced out‐of‐band signal rejection since input and output coupling is effected through different modes.
