    This paper describes the microcleaved facets (MCF) process developed for AlGaAs/GaAs laser fabrication which can avoid the previous substrate cleavage and therefore be applicable to preparing both discrete short-cavity lasers and optoelectronic integrated circuits (OEIC's). An AlGaAs/GaAs double heterostructure ridge-waveguide laser with an extremely short cavity length, namely 20 μm, was fir... View full abstract»

    A simple three-mirror composite laser cavity is analyzed and optimum structures proposed in terms of the position of the central reflector and the value of its reflectivity in order to give single longitudinal mode operation. Two optimum structures are discussed, the first corresponding to relatively long cavities where a large period in the gain modulation is required in order to avoid a jump to ... View full abstract»

    Optimum Conditions for stable operation of an injected TEA-CO2laser with high-power output have been pursued both theoretically and experimentally. The stability of injection locking as well as the obtainable peak power was analyzed based on a transient mathematical model which deals with buildup of the electric fields. Predicted dependence of injection locking on the injection intensit... View full abstract»

  • Two-mode multiline laser stabilization using a Fabry-Perot filter under analog and digital computer control

    A scanning Fabry-Perot interferometer, servolocked to one of the output frequencies of a multiline laser, is used as a tracking filter so that a second servoloop can accurately stabilize that laser line to features of its intensity-versus-frequency profile. More stable locks occur where two longitudinal modes lase simultaneously than where the single-mode line intensity is maximized. Both analog a... View full abstract»

    A CW laser pumped emerald laser is reported, A 34 percent output power slope efficiency is observed with longitudinal pumping by a krypton laser in a nearly concentric cavity. The laser has been tuned from 728.8 to 809.0 nm, Losses in emerald are larger than those of alexandrite determined in a similar cavity. Our data also indicate that the excited state absorption minimum is shifted from that of... View full abstract»

    We derive a novel rate equation system for a laser consisting of two coupled cavities arranged in tandem. The derivation of the photon rate equations is based on classical electromagnetic theory, while the rate equations for the electrons are written down heuristically in analog with the conventional laser rate equations. This paper discusses the initial numerical evaluation of our coupled-cavity ... View full abstract»
