摘要： Longitudinal diode-pumped solid-state lasers currently have maximum power outputs of no more than a few watts. By using resonators with several reflection sites inside the active medium (3), the output power of these lasers can be boosted accordingly. The novel configuration proposed here differs from known designs in being far easier to handle and less costly to manufacture.

摘要： A semiconductor laser-excited solid-state laser device which is constituted by mounting a sub-mount, an LD bar, and a light guiding duct on the LD package main body of a semiconductor laser and inserting the emitting section of the LD bar into the light guiding duct. Then a gold-metallized insulating plate is welded to one side of the LD package main body and the LD bar and gold-metallized part are connected by wire bonding. The light guiding duct is constructed so that the duct can directly transmit exciting light to a laser medium and the periphery of the laser medium can be surrounded by a light condenser. When an electric current is made to flow to a cathode from the LD package main body, the LD bar emits LD exciting light and the laser medium is excited, resulting in laser oscillation. Therefore, a highly reliable and highly efficient LD-excited solid-state laser device which can be assembled easily and can be manufactured at a low cost can be obtained.

摘要： A diode pumped laser includes a resonator mirror and an output coupler, defining a laser resonator with a resonator optical axis. A strong thermal lens laser crystal with a TEM00 mode diameter is mounted in the resonator along the resonator optical axis. A diode pump source supplies a pump beam to the laser crystal in the laser resonator, and produces an output beam with a diameter larger that the TEM00 mode diameter to reduce thermal birefringence. A power source supplies power to the diode pump source. A polarizing element can be positioned in the resonator, along with an aperture stop. The laser operates well over a large range of pump powers. Its slope efficiency in the TEM00 mode is greater than 40 %, with an overall efficiency greater than 25 %. One of the lasing crystals used is Nd:YVO4. This material exhibits high gain and a short upper state lifetime. These properties make it attractive in designing a Q-switched laser, or one that is insensitive to optical feedback. Another material is Nd:YAG. The technique of optimizing the pump beam spot size is found to minimize loss due to thermal birefringence.
