“…Since all these effects are small, the lasers with Fabry-Perot cavities are quasi-isotropic and orthogonally polarized modes with the same longitudinal index have equal lasing thresholds and similar lasing frequencies, and under these conditions unstable lasing is possible [5,11]. Similar problems have already been considered in a variety of situations, mostly for He-Ne [14][15][16][17][18][19][20] and then YAG [21,22] and diode [23,24] lasers and more recently Vertical Cavity Surface Emitting Lasers (VCSEL) [12]. As far as microchip lasers are concerned, there have been few systematic studies of their polarization dynamics.…”

UDC 621.373This paper is devoted to the polarization dynamics of a longitudinally monomode bipolarized Nd:YAG laser: the low-frequency polarization dynamics of a microchip laser is studied experimentally and theoretically. The intensities and the relaxation oscillation spectrum of orthogonally polarized modes versus the direction of pump polarization is observed. A phase-sensitive model of a longitudinally monomode bipolarized solid-state laser with linear polarized diode laser pump is developed to account for the experimental observations.

“…The experimental conditions are not always specified or not relevant to the present work because some use non-polarized pumping. However, the following conclusions can be deduced [5,11,21,22]:…”

“…Usually the radiation of these lasers is concentrated in certain modes of oscillations. Multi-mode (in particular, double-mode) solid-state lasers are widely used in fundamental scientific research and in applications [1][2][3]. Double-mode lasers (DMLs) have prospects for use in the creation of precise ranging systems.…”

Peculiarities of mode competition in a double-mode diode-pumped Nd:YAG laser

Abstract:The mode competition in a double-mode diodepumped Nd:YAG laser is studied theoretically and experimentally. In particular, the influence of various laser parameters on the steady-state double-mode regime for parallel and orthogonal polarization of the modes is studied. It is shown that the establishment of steady-state double-mode lasing is accompanied by relaxation oscillations more complicated than for single-mode lasing. It is found that the scanning rate of the cavity modes influences the character of the relaxation oscillations. The value of the double-mode lasing range d as a function of ω 12

“…Dual-polarization oscillations (DPO) in LD-pumped microchip solid state lasers are useful for a variety of applications, ranging from heterodyne interferometry [1,2,3] to optical communications [4,5]. DPO has also attracted much attention from the physics point of view, and similar DPO and related phenomena, including polarization mode hopping in vertical cavity semiconductor lasers (VCSELs) [6,7,8,9]; dynamic pattern formations in pulsed solid-state lasers [10], have been reported.…”

Dual-polarization oscillations (DPO) on different transitions have been observed for the first time in a mirror-coated thin-slice Nd:GdVO(4) laser possessing a large fluorescence anisotropy with laser-diode (LD) pumping. Oscillation spectra, input-output characteristics, pump-dependent pattern formations and noise power spectra are studied experimentally. Simultaneous oscillations of orthogonally-polarized different (higher-order) transverse modes and the resultant violation of inherent antiphase dynamics in multimode lasers have been demonstrated. The experimental results have been explained in terms of the reduced three-dimensional cross-saturation of population inversions among orthogonally-polarized modes peculiar to LD-pumped wide-aperture anisotropic lasers, in which a pumped area is larger than a lasing beam diameter.
