Oscillation Spectra in Metal Vapor Lasers

Pulsed Metal Vapor Lasers Phase Ii Quarterly Report

Advances in Laser Diode and OPSL Technologies Render Ion and Metal Vapor Lasers Obsolete

There are now many applications for visible and UV continuous wave lasers in the tens to hundreds of milliwatts power range, covering e.g. life sciences, metrology and inspection. Originally these were dominated by ion and HeCd metal vapor lasers due to their early availability. However, these sources are characterized by numerous well-known practical deficiencies (e.g., large size, electrical ...

Indirectly Pumped 3.7 THz InGaAs/InAlAs Quantum-Cascade Lasers Grown by Metal-Organic Vapor-Phase Epitaxy

Device-performances of 3.7 THz indirect-pumping quantumcascade lasers are demonstrated in an InGaAs/InAlAs material system grown by metal-organic vapor-phase epitaxy. The lasers show a low threshold-current-density of ~420 A/cm and a peak output power of ~8 mW at 7 K, no sign of parasitic currents with recourse to well-designed coupled-well injectors in the indirect pump scheme, and a maximum o...

Semiconductor Lasers and Kolmogorov Spectra

In this letter, we make a prima facie case that there could be distinct advantages to exploiting a new class of finite flux equilibrium solutions of the Quantum Boltzmann equation in semiconductor lasers.

Modeling and characterization of InAs/GaAs quantum dot lasers grown using metal organic chemical vapor deposition

We report on the lasing characteristics of threeand five-stack InAs/GaAs quantum dot QD lasers grown by metal organic chemical vapor deposition. By increasing the number of stacked dot layers to 5, lasing was achieved from the ground state at 1135 nm for device lengths as short as 1.5 mm no reflectivity coatings . The unamplified spontaneous emission and Z ratio as a function of injection curre...
