Abstract

A mode-locking solid-state laser apparatus is a soliton-type mode-locking solid-state laser apparatus, having a solid-state laser medium, a saturable absorption mirror and a negative group velocity dispersion element in a resonator, wherein the solid-state laser medium and he absorption mirror are disposed at a distance not greater than twice a Rayleigh length. Then, the absorption modulation depth Delta R of the saturable absorption mirror is set to a value not less than 0.4%, and the absolute value lDl of a total intracavity dispersion amount when light having a predetermined wavelength makes one round trip in the resonator, which is represented by the following mathematic expression (1), is set within a pulse bandwidth in which operation modes other than a fundamental period soliton pulse can be suppressed by the saturable absorption mirror.

Description

technical field [0001] The present invention relates to a solid-state laser device, and more specifically, to a mode-synchronized solid-state laser device that is easy to downsize and can realize short-pulse operation. Background technique [0002] Conventionally developed solid-state laser devices use a semiconductor laser (LD) as an excitation light source to excite solid-state laser media (laser crystals, ceramics, glass, etc.) to which rare earth ions or transition metal ions are added. Among them, short-pulse laser devices that generate so-called short-pulse light in the picosecond to femtosecond region have been researched and advocated in many application fields such as medical treatment, biology, machinery industry, and measurement, and after actual verification, some of them have been put into practical use. . [0003] This laser produces short pulses through an action known as mode synchronization. Briefly, the so-called mode synchronization refers to a phenomeno...
