| Abstract: | A Tm:germanate fiber laser produced >0.25 mJ/ pulse in a 45 ns pulse. It is capable of producing multiple Q-switched pulses
from a single pump pulse. With the addition of a diffraction grating, Tm:germanate fiber lasers produced a wide, but length
dependent, tuning range. By selecting the fiber length, the tuning range extends from 1.88 to 2.04 μm. These traits make Tm:germanate
lasers suitable for remote sensing of water vapor.
