摘要
A laser system and method generate milliwatt-power pump light by a fiber-coupled laser diode with a single-mode integrated fiber housed in a pump enclosure. The milliwatt-power pump light is conveyed from the single-mode integrated fiber out of the first enclosure into one end of a single-mode fiber cable that is external to the pump enclosure. The milliwatt-power pump light is conveyed from an opposite end of the external single-mode fiber cable into one end of a single-mode resident fiber disposed internally within a laser-head enclosure. A crystal housed in the laser-head enclosure is pumped with the milliwatt-power pump light that exits into free space from an opposite end of the single-mode resident fiber onto a face of the crystal, to produce stable milliwatt-power single-mode laser light having a frequency stability of less than 3 MHz per minute. The stable milliwatt-power single-mode laser light is emitted from the laser-head enclosure.
