摘要： An ultra-low heat laser that does not rely on florescence cooling. Generally, the inventive laser includes a pump source operable at a pump frequency and a gain medium disposed to receive energy from the source and lase at a frequency close to the pump frequency. In the illustrative embodiment, the laser is a solid state laser having a gain medium which is resonantly pumped to lase at a frequency within 5% of the pump frequency. However, in the best mode and in accordance with the present teachings, the gain medium lases at a frequency within 1% of the pump frequency. In the illustrative embodiment, the laser gain medium ion has a rich Stark energy level structure and the laser active gain medium has oscillator strengths at transitions wavelengths that allow an ultra-low quantum defect operation. The pump source has a wavelength output centered to correspond to a predetermined pump band and an emission band subtended by an absorption bandwidth thereof.

摘要： A laser. The novel laser includes a gain medium, a pump source adapted to optically excite the gain medium in a first location, and a resonator adapted to extract energy from the gain medium in a second location distinct from the first location. In an illustrative embodiment, the gain medium is comprised of a plurality of solid-state gain particles suspended in a fluid. The gain medium is adapted to flow, and optical excitation of the gain medium occurs outside of the resonator. In a preferred embodiment, the flow velocity and the density of gain particles in the gain medium are adjusted for optimal absorption efficiency during optical excitation and then for optimal extraction efficiency in the resonator. In addition, the resonator may be shaped for optimal extraction efficiency, while pump modules that hold the gain medium during optical excitation are shaped for optimal absorption efficiency.

摘要： A solid-state suspension laser. The novel laser includes a gain medium comprised of a plurality of solid-state gain particles suspended in a fluid. The laser also includes a pump source for pumping the gain particles and a resonator for amplifying and outputting laser light generated by the gain medium. In an illustrative embodiment, the gain medium is adapted to flow, and the pumping of the gain medium occurs outside of the resonator. The flow velocities and the densities of the gain particles in the gain medium can be optimized for optimal absorption efficiency during the pumping and/or for optimal extraction efficiency in the resonator as well as for overall laser performance optimization, including power, efficiency and beam quality scalability.
