| Research Abstract |
We performed the research on the development of a novel technique toward controlling transverse lasing patterns and its applications with laser-diode-pumped microchip solid-state lasers. We clarified peculiar lasing pattern formation, which is inherent to wide-aperture thin-slice or microchip cavity configurations with laser-diode end pumping, associate optical spectral characteristics, polarization properties and dynamic effects. We have developed the promising technique for controlling transverse lasing patterns and generating a new class of optical vortex and vortex array laser beams. In conjunction with the research of mode control, we achieved the great advancement of self-mixing microchip solid-state laser metrology systems and widened their application schemes.
