Abstract

The conditions of phase locking of a three-channel holographic Nd:YAG laser system based on self-pumped phase-conjugate oscillators emitting giant 100-mJ, 60-ns monopulses in each of the channels are investigated experimentally. The pulse-to-pulse stable self-phase-locking of the laser system with a pulse repetition rate up to 20 Hz is obtained. The mutual coherence of laser channels was increased up to 0.87 by separating the controlling channel which initiates lasing in a set of controllable channels generating synchronous monopulses.

Oscillation dynamics of a phase-locked three-channel holographic Nd:YAG laser system

Basiev, Tasoltan T ; Gavrilov, A V ; Smetanin, S N ; ... - Quantum Electronics (Woodbury, N.Y.)

A method of phase locking of a parallel multichannel laser system by holographic gain gratings in the active laser medium at a long-range holographic coupling of laser channels is developed. The oscillation dynamics of a three-channel holographic Nd:YAG laser system is simulated by considering the phase-locking conditions depending on the relative gain mismatch in laser channels. The conditions of lasing with the gain-selected control laser channel are found under which controlled channels are phase-locked even in the case of the threefold difference in their gains. (lasers)

Study of diffraction-coupled lasing in a set of lasers with self-pumped phase-conjugate mirrors on gain gratings in the case of short-range coupling

Basiev, Tasoltan T ; Osiko, Vyacheslav V ; Gavrilov, A V ; ... - Quantum Electronics (Woodbury, N.Y.)

Compact schemes of a multichannel holographic laser system with short-range coupling and increased efficiency of single-mode lasing are developed for low-gain laser media operating not only at the fundamental laser transition but also at other laser transitions of the Nd:YAG crystal. The numerical simulation shows that the maximum possible number of laser channels can be increased by equalising their parameters. The possibility of phase locking of two loop Nd:YAG lasers without a nonreciprocal element with the free-running single-mode lasing efficiency up to 0.64% and the contrast of the interference pattern of the output beams exceeding 0.5 is shown experimentally.

Phase locking of optically coupled lasers by gain gratings in an active medium

Basiev, Tasoltan T ; Osiko, Vyacheslav V ; Gavrilov, A V ; ... - Quantum Electronics (Woodbury, N.Y.)

A method of phase locking of optically coupled lasers by gain gratings in an active medium is proposed. The criterion for phase locking is determined and optimal relations between the energy parameters of waves upon four-wave mixing are found. Two-channel parallel laser systems based on self-phase-conjugation loop oscillators are studied and the possibility of their phase locking with the phasing degree up to 0.9 is shown.

Continuous-wave Nd:YAG laser with passive stabilization of self-mode locking

Gusev, A.A. ; Kruzhalov, S.V. ; Lvov, B.V. ; ... - Opt. Spectrosc. (Engl. Transl.); (United States)

In this paper, which is a continuation of Ref. 1 )A. A. Gusev et al., Opt. Spektrosk. 55, 928 (1983) (Opt. Spectrosc. 55, 560 (1983))), we present the results of an experimental investigation of the effect of a passive (unpumped) intracavity Nd-YAG element in the self-mode locking of a YAG laser. It is shown that introduction of a passive element considerably increases the stability of this mode to different perturbing factors and enables it to operate at higher output-power levels. In addition, the emission-pulse length is reduced, and the range of variation of the pulse repetition frequency is extended.
Self-starting additive-pulse mode locking of a ND:YAG Laser

Liu, L.Y. ; Huxley, J.M. ; Ippen, E.P. ; ... - Optics Letters; (USA)

We report additive-pulse mode locking of lamp-pumped Nd:YAG lasers at both 1.06 and 1.32 {mu}m. Under completely self-starting conditions, stable cw mode-locked trains of 6-psec pulses have been achieved at an average output power of 2.4 W.
