We report single-frequency operation of a Nd3+: YVO4 laser in geometric modes when its
cavity is strongly frequency degenerate. These geometric modes closely resemble closed …

Abstract SiO 2, ZrO 2, B 2 O 3 and MgO oxides and their combinations were used as
sintering aids for preparation of yttrium aluminum garnet (YAG) ceramics doped by Nd 2 O 3 …

The influence of transverse mode locking in critical cavity configurations on the threshold
pump power of diode end-pumped solid-state lasers was investigated both theoretically and …

We find that soft-aperture Kerr-lens mode locking (SAKLM) in a Ti: sapphire laser always
takes place around certain discrete cavity configurations accompanied by peculiar beam …

A period-doubling route to chaos with nonstationary transverse pattern is observed in a
diode-pumped Nd: YAG laser with a Cr^ 4+: YAG saturable absorber. The nonlinear …

We studied both numerically and experimentally the transverse modes near degenerate
resonator configurations such as g_1g_2= 1/4, 1/2, 3/4 in a simple plano–concave Nd …

Transverse mode locking in a diode end-pumped Nd: YAG laser with up to~ 140 cm
resonator length was investigated. It was found that for each resonator degeneracy, there …

A straightforward method for converting the symmetry of a diode end-pumped laser with an
annular pump beam has been proposed. By introducing an étalon into the cavity, we …

We experimentally show, for the first time to our knowledge, that a diode-pumped Nd:
YVO_4 laser can operate with multipass transverse (MPT) modes that self-reproduce after …

Far-Field non-Gaussian fundamental transverse modes have been obtained in CW end-
pumped Nd: YVO4 microchip laser for particular cavity lengths. Such profiles appear at …
