Abstract
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.
