Lasing was achieved in solutions of coumarin 7 (coumarin 535) pumped by an He?Sr recombination laser (430.5 nm). Jet and cell versions of the dye laser were used. The average output power of the jet laser was 15 mW, whilst that of the cell laser was 30 mW. The tuning range was 499?557 nm and the conversion efficiency was ~ 5%. A distinguishing feature, compared with dye lasers pumped by a copper vapor laser, was that the duration of the lasing pulse was an order of magnitude greater ( ~ 0.2 ?s).

A method is described for determining the reflection coefficients of high-density mirrors, based on the use of a mode-locked laser and a sensitive detector with a fast time resolution. The laser light is transmitted through an optical resonator formed by the investigated mirrors. The measured delay in the decay of a light pulse gives the damping time of the optical resonator. This is related to its Q factor determined by the reflection coefficients of its mirrors.

An investigation was made of a resonant optical parametric oscillator based on the resonant third-order nonlinearity in sodium vapor. Synchronous bichromatic pumping was provided by picosecond optical pulses of good spectral quality. Dependences of the main parameters of the output radiation of a four-photon optical parametric oscillator on the sodium concentration and on the optical resonator length were obtained.

An experimental investigation was made of the energy conversion efficiency and of the effects of stimulated Brillouin scattering and of optical breakdown, limiting the maximum energy density obtained from several phosphate and silicate neodymium glasses when the duration of the output pulses was 50–150 ns. The experimental results were used to develop a numerical model for calculation of the gain allowing for these processes. A design was developed for an amplifier with ultimate radiation characteristics.

A calculation is made of the threshold sensitivity of a laser-interferometric antenna with a phase-conjugating resonator. The use of such a resonator for compensation of technical fluctuations of the signal laser is limited by the stability of the frequency of the reference waves pumping a nonlinear mirror. Recommendations relating to engineering design of an antenna with parallel arms are given.
