Long cavity laser system including frequency doubling long cavity fiber optic laser system |
摘要 |
A polarization controlled laser system receiving a pump laser beam includes a long laser cavity for precluding mode hopping. Preferably, the long laser cavity is defined by first and second dichroic reflectors, a rare earth doped optical fiber disposed between the first and second dichroic reflectors for amplifying the pump laser beam to thereby produce an amplified laser beam, a polarization controller for controlling polarization of the amplified laser beam, and a polarization selector for selecting the polarization of the amplified laser beam. The polarization selector can include a polarizing optical fiber while the polarization controller advantageously may include a polarization maintaining optical fiber. Alternatively, the rare-earth doped optical fiber, the polarization controller, and the polarization selector are all formed from a single polarizing rare-earth doped optical fiber. The polarization controlled laser system may be converted to a frequency doubled polarization controlled laser system by adding a doubling crystal to the long laser cavity. Methods for generating polarization controlled laser beams using a long laser cavity formed from a rare-earth doped optical fiber are also described.
