摘要： A laser apparatus, system and method include a laser crystal formed of thulium-doped yttrium-lithium-fluoride, and a laser diode arranged in proximity to the laser crystal. The laser diode is capable of emitting a first laser light which is suitable for use as a pump beam for causing lasing to occur in the laser crystal. In response to the first laser light from the laser diode, the laser crystal emits a second laser light at a wavelength which is relatively highly-absorbed by organic tissue and/or water. The second laser light is therefore well-suited to medical applications, for example, and can be used to irradiate organic tissue for medical treatment.

摘要： A tunable ytterbium-doped solid-state laser has a laser cavity defined a r of mirrors, a laser medium positioned in this cavity, means for pumping the laser medium, and means for tuning the output of this laser medium to a selected wavelength within a wavelength range. The laser medium has a host material doped with enough ytterbium ions to produce a longitudinal mode laser emission when the laser medium is pumped. In a most preferred embodiment, the laser emission is frequency-doubled and tuned to a wavelength corresponding to a Fraunhoffer line in the solar spectrum.

The laser includes a laser cavity defined by spaced, opposed reflective member forming a reflective path therebetween; a host laser crystal disposed in the cavity; an acousto-optic modulator disposed between the host laser crystal and one reflective member for modulating the output of the host laser crystal; and a birefringent filter, disposed in the laser cavity between the host laser crystal and the one reflective member, for tuning the laser emission to any one of a plurality of wavelengths within a range between 1.86 .mu.m and 2.14 .mu.m. A pump source pumps the host laser crystal at a wavelength of substantially 785 nm. A collimating plano-convex lens is disposed so that the planar face thereof faces the laser crystal. A mechanical device adjusts the length of the reflective path by axially displacing the one reflective member in the laser cavity so as to match the cavity round trip time to the second harmonic of the drive frequency of the acoustic-optic modulator.
