Toward Nonepitaxial Laser Diodes
Chemical Reviews, 2023Thin-film organic, colloidal quantum dot, and metal halide perovskite semiconductors are all being pursued in the quest for a wavelength-tunable diode laser technology that does not require epitaxial growth on a traditional semiconductor substrate. Despite promising demonstrations of efficient light-emitting diodes and low-threshold optically pumped ...

AbstractDiode laser is a solid state Gallium Aluminium Arsenide (Ga AIAs) laser with a wavelength of approximately 800 nm (near infrared radiation). It has a similar penetration to, and absorption within the ocular tissues as, Krypton red. Diode laser trabeculoplasty (DLT) was carried out on 20 glaucomatous eyes resulting in a mean fall in intraocular ...

Semiconductor Diode Laser Endophotocoagulation
Ophthalmic Surgery, Lasers and Imaging Retina, 1989ABSTRACT We successfully used a semiconductor diode laser to deliver endophotocoagulation burns to the retina of a rabbit. The diode laser employed emits light at a wavelength of 817 nm (near infrared). It has a power output of up to 1.0 W in the continuous-wave mode, equivalent to the capability of current argon laser endophotocoagulators. A

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.

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.
