Laser-diode holographic recording
Optics Letters, 1986We report the recording of optical holograms in both holographic plate films and thermoplastic film using a commercial single-mode laser diode having a wavelength of 787.3 nm. Holographic film characteristics and laser-diode coherence length studies as well as experimental results with simple plane-wave holograms are discussed.

Physical Review Letters, 1987
A foilless diode usually requires an externally applied magnetic field to control expansion and transport of a relativistic electron beam. A new foilless diode has been developed that does not require an external magnetic field. A low pressure organic gas is introduced into the diode and the transport region.

2006 IEEE LEOS Annual Meeting Conference Proceedings, 2004
The 20-year-evolution of high-power laser diodes with a multitude of device designs that explore various practical applications is presented. The four major applications for high-power diode lasers, namely pumps for EDFAs, YAG rods, disk lasers and fiber lasers have a tremendous impact on the selection process in this evolution.

Directly diode-laser-pumped Ti:sapphire laser
Optics Letters, 2009A directly diode-laser-pumped Ti:Al(2)O(3) laser is demonstrated. Using a 1 W, 452 nm GaN diode laser, 19 mW of cw output power is achieved in a potentially portable format. Pumping at this short wavelength induces a loss at the laser wavelength that is not seen for the more typical green pump wavelengths. This effect is characterized and discussed.

Diode-pumped Cr:LiSrAlF_6 laser
Optics Letters, 1991A Cr:LiSrAlF(6) laser is diode pumped with both commercial 10-mW visible laser diodes and a higher-power 100-mW cw, 265-mW pulsed diode. Polarization combination of pump diodes to reach threshold is demonstrated with two low-power lasers. Pumping with the high-power diode produced powers of 19.9 mW cw and 78 mW pulsed.
