Mid-IR transition metal lasers

SPIE Proceedings, 2007
Transition metal ions have been of great interest from the beginning of laser development because of their broadband emission. The first demonstration of a transition metal laser used Ni 2+ as the active ion in 1963. Other transition metal ions such as Co 2+ have also been developed as lasers but low cross sections and the need for cryogenic ...

Mid-IR interband cascade lasers

Conference Proceedings. LEOS '97. 10th Annual Meeting IEEE Lasers and Electro-Optics Society 1997 Annual Meeting, 1997
The multi-stage interband cascade laser (ICL) represents a fundamentally new class of semiconductor coherent IR source. Numerical simulations predict that it will combine the advantages of low threshold currents, high operating temperatures, and high output powers at wavelengths from 2.5 /spl mu/m to 7 /spl mu/m.

Status of mid-IR fibers

Optical Fiber Communication Conference, 1989
Fluoride glasses are being considered for use in long distance mid-IR transmitting optical fibers. The multiphonon edge of these fibers is shifted to longer wavelengths compared with silica fibers. The intrinsic loss is, therefore, lower (≤0.01 dB/km) and occurs at −2.5 μm.

Ultrafast tunable mid IR source

2011 International Conference on Infrared, Millimeter, and Terahertz Waves, 2011
We report on a Laser source, emitting in the mid-IR spectral range. A mode-locked Nd: YVO Laser is used as a pump Laser, followed by two nonlinear frequency conversion steps (OPG, DFG). The broad-band output beam is tunable between 9 μm and 13 μm, with average powers up to 10 mW. Further extension of the tuning range is possible.

Advances in Mid-IR Materials

2007 Conference on Lasers and Electro-Optics (CLEO), 2007
Improved processing continues to reduce absorption losses in new and old bulk birefringent nonlinear optical crystals, while advances in all-epitaxial grown QPM GaAs promises to extend efficient, high-power frequency conversion to longer wavelengths.

Mid-IR Difference Frequency Generation

2007
The availability of continuously tunable narrow-band laser sources emitting in the mid-infrared region of the electromagnetic spectrum between 2.5 μm and 15 μm is important for a large variety of applications. One way to achieve both broad tunability and narrow linewidth is frequency conversion in a nonlinear optical material, in particular difference ...

Gas Phase Mid-IR Lasers.

1996
Abstract : A program to develop and apply new mid-IR lasers for Air Force applications is described. Optically pumped lasers that operate either on vibrational or electronic transitions are discussed. Systems include molecular iodine as an electronic transition laser and HF, DF, and HCl as vibrational laser systems.
