Direct diode pumped Ho:YAG generated laser pulses at 2.12 μm with an optical to optical slope efficiency of 0.24. Ho:YAG and Ho:LuAG laser rods were evaluated with both wide and narrow bandwidth pump diodes. The laser wavelength varies with the leve

Tm-doped alkali germanate glass is investigated for use as a laser material. Spectroscopic investigations of bulk Tm-doped germanate glass are reported for the absorption, emission and luminescence decay. Tm:germanate shows promise as a fiber laser w

A diode-pumped laser amplifier model is derived from first principles and applied to a Nd:YAG amplifier operating on the 4F 3/2 to 4I 9/2 transition at 0.946 μm. The effects of amplified spontaneous emission are included in the model and the additio

A room temperature, directly diode pumped Ho:LuAG laser oscillated for the first time. Direct pumping of the Ho upper laser manifold maximizes efficiency, minimizes heating, and eliminates Ho:Tm energy sharing. Design and performance are presented.

Time constants for population density rise and decay are often unequal. Asymmetric time constants result from: ground state depletion, up conversion, and amplified spontaneous emission. All these effects were modeled and Tm :germanate experiments sup

A novel method of making a line tunable, visible and near ultraviolet, laser source is proposed and demonstrated. It requires only a single laser and 2 nonlinear crystals. It can produce outputs with wavelengths that cover much of the spectrum from 0

Tm:germanate fiber lasers can tune between 1.88 and 2.04 µm, depending on the length. Optimized pulsed operation yielded thresholds of 62 mJ and slope efficiencies of 0.25, even with a low launch efficiency. Q-switching achieved.
