- Composite Yb:YAG/SiC-prism thin disk laserG A Newburgh
US Army Research Laboratory, RDRL SEE O, 2800 Powder Mill Rd, Adelphi, MD 20783, USA
Opt Express 18:17066-74. 2010..5. This demonstration opens up a viable path toward novel thin disk laser designs with efficient double-sided room-temperature heatsinking via materials with the thermal conductivity of copper on both sides of the disk...
- Resonantly diode-pumped Ho3+:Y2O3 ceramic 2.1 µm laserG A Newburgh
U S Army Research Laboratory, RDRL SEE O 2800 Powder Mill Road, Adelphi, Maryland 20783, USA
Opt Express 19:3604-11. 2011..1. We have measured the absorption and stimulated emission cross sections of Ho3+:Y2O3 at 77 K and 300 K and present the calculated gain cross section spectrum at 77 K for different excited state inversion levels...
- Highly efficient dual-wavelength laser operation of cryo-cooled resonantly (in-band) pumped Ho3+:YVO4 laserG A Newburgh
U S Army Research Laboratory, Adelphi, Maryland 20783, USA
Opt Lett 37:3888-90. 2012..We have achieved laser operation with a maximum slope efficiency of ~92%. This is, to the best of our knowledge, the highest slope efficiency ever demonstrated for any Ho(3+)-doped laser...
