We have demonstrated an upconversion-pumped blue laser on the (1)G(4)-(3)H(6) band of Tm:YAG at cryogenic temperatures. Measurements were also made to assess the possibility of room-temperature upconversion-pumped lasers in Tm:YAG on both the (1)G(4)

A room-temperature Tm:YVO4 laser at 1.94 μm has been demonstrated for the first time to our knowledge. This laser is characterized by a broad bandwidth and a large absorption cross section for the 800-nm pump band. A slope efficiency of 25% was obta

We report the first observation to our knowledge of coherent emission at 473 nm from an intracavity-doubled Nd:YAG microlaser. The d32 coefficient of potassium niobate was used in a 90-deg, temperature-tuned, Type I phase-matching configuration to ge

Two-wave mixing absorption in a supersonic beam containing I2 has been studied. The results are in agreement with theory for probe intensities comparable with the pump intensity. However, at very low probe-beam intensities, the absorption deviates su

The feasibility of using a severely aberrated pump beam to amplify effectively without distortion a diffraction-limited Raman beam has been studied. In these experiments the XeCl laser served as the pump and H(2) as the Raman medium. Degradation of t

The laser-heated pedestal growth technique has been used in conjunction with a unique feedstock preparation method to grow small single crystal rods of Nd-doped and Tm-doped YLF. Starting powder materials were purified by hydrofluorination and melted

Cerium has been doped in both LiCAF and LiSAF. However, each host has some intrinsic problems resulting in scatter and thermal expansion coefficient issues, respectively. In order to optimize the laser host, crystals were grown on various composition
