“…This mechanism of stabilization, achieved by forcing the laser to operate in the one-mode regime, is similar to other approaches presented in the literature, where the stabilization is obtained by inserting into the laser cavity an additional element like an etalon [Baer 1986] or a birefringent crystal [Nagai et al, 1992, Fan, 1991. However, the method proposed here seems to be a better solution, since no additional element is involved.…”

“…Moreover, it has been predicted analytically [James et al, 1990b] and confirmed experimentally [Magni et al, 1993] that when the number of oscillating longitudinal modes is set to be sufficiently large (for example, by increasing the length of the laser cavity) the output of the laser becomes stable. Besides, the green problem can also be avoided in the case of a single mode operation of the laser, which can be obtained, for example, by use of an intracavity etalon [Baer, 1986] or a birefringent filter [Nagai et al, 1992, Fan, 1991 2 The main goal of this paper is to continue the investigations of the green problem. The fact that the cross-saturation coefficient is modulated by the spatial hole-burning effect is taken into account.…”

In this paper possibilities of a stabilization of large amplitude fluctuations in an intracavity-doubled solid-state laser are studied. The modification of the cross-saturation coefficient by the effect of spatial hole-burning is taken into account. The stabilization of the laser radiation by an increase of the number of modes, as proposed in [James et al., 1990b, Magni et al., 1993, is analyzed. It is found that when the crosssaturation coefficient is modulated by the spatial hole-burning the stabilization is not always possible. We propose a new way of obtaining a stable steady-state configuration based on an increase of the strength of nonlinearity, which leads to a strong cancellation of modes, so that during the evolution all of the modes, but a single one, are canceled.Such a steady-state solution is found to be stable with respect to small perturbations.

“…We chose a linear optical scheme with a Brewster plate and a nonlinear KTP crystal previously used for Nd:YAG [5] and Nd:YVO4 [6] lasers. Singlelongitudinal-mode (SLM) generation in such lasers has already been investigated theoretically and experimentally (e.g., [4,7]).…”

In this paper the development and optimization process of single frequency, diode pumped Nd:YVO 4 /YVO 4 /KTP microchip laser operating at 532nm is presented. A birefringent filter formed by beam displacer (undoped YVO 4 crystal) and KTP crystal was used to obtain single mode operation. As a final result of optimization miniature, monolithic laser resonator was elaborated. The laser generated Gaussian beam with quality better than M 2 <1.2 and maximum single frequency output power at the level of 160mW @ 532 nm. The optical to optical efficiency (532nm to 808nm) was at the level of 16,8% at the maximum single frequency output power.
