Abstract: |
Fiber lasers have attracted
significant attention in last several years because of many
technology breakthroughs and commercial business successes. Most
fiber lasers use rare-earth ions doped silica fibers as the gain
media. However, in many cases silica fiber is not the ideal
host. Multi-component specialty glass fibers are good
alternatives because of their unique features such as low
co-operative up-conversion coefficient, large mode field
diameter, and short active fiber length. In this presentation, I
will present highly erbium and ytterbium doped phosphate glass
fibers for narrow linewidth single frequency fiber lasers near
1.5 and 1 microns, and thulium doped germanate glass fiber 2
micron fiber lasers with slope efficiency great than 70%.
Brillouin fiber laser, Brillouin based fiber sensing, and
potential application for wireless-over-fiber will be discussed.
THz and GHz generation using Q-switched high power fiber lasers
will also be described in this presentation. |
