    Extension of the molecular rate equations for a dye laser to include the effect of very rapid transverse flow shows that spatial transit times comparable to the dye intersystem crossing time prevent the buildup of a large triplet state population. This new technique enables limiting the triplet-triplet absorption loss without using triplet quenching agents. An air-turbine driven rotating disk of r... View full abstract»

    A method for noninterference sampling of high-power CO2laser beams is described. The technique employs an ultrasonic diffraction grating generated in the air path across a laser beam. A very small fraction (sim10^{-7}) of the main beam is diffracted through a small angle (sim2deg) on either side. Profiles of Gaussian and "donut" modes from low-power CO2l... View full abstract»

    Results are presented on observations of activeQswitching of the CO2laser by intracavity Stark modulation with a sine-wave or square-wave electric field using methyl chloride and 1-1 difluoroethane. PassiveQswitching of theRbranch of the 10.4-μm band by methyl fluoroform, at a repetition rate variable by a dc Stark field, is also reported. View full abstract»

    The amplification of a laser pulse has been evaluated numerically for three different laser media, viz., Nd-POCl3, Nd-glass, and ruby. An energy-utilization factor is defined and calculated for the same media. Finally, a dimensionless plot is given from which the amplification can be calculated for arbitrary numerical conditions.

    A double-discharge hydrogen fluoride chemical laser using SF6+ C4H10and SF6+ H2is described. A maximum pulse energy of 102.5 mJ is reported, with a peak power of about 400 kW. The energy density is 300 mJ/l, and the electrical efficiency is 0.6 percent. View full abstract»

    A three-frequency 10.6-μm heterodyne receiver was demonstrated experimentally. Narrow-band reception of a 40-MHz IF was realized without tracking of the carrier frequency by the local oscillator laser. A signal-to-noise ratio within 1 dB of the theoretical value was measured for large SNR. View full abstract»

    Optical pulses up to 1.25 Gbit/s were obtained with a Nd3+:YAG laser by multiple mode locking. The carrier frequency of mode-locked pulses was tuned through several tens of gigahertz by tilting an intracavity tuning etalon. Some detuning effects in forced mode locking will be also presented.

    A simple analytical model is presented to describe the delay τcbetween flashlamp initiation and laser-pulse onset in the flash-photolysis HF chemical laser. The predictions of the model agree well with experiments concerning the functional dependence of τcon pressure, flashlamp intensity, optical cavity loss, and the absolute magnitude of τc. This de...
