Observation of Long Turn-On Delay in Pulsed Quantum Cascade Lasers
نویسندگان
چکیده
We present an experimental study of the turn-on delay in pulsed mid-infrared quantum cascade lasers. report unexpectedly long time depending on pumping current, which does not agree with conventional theoretical predictions for step-like excitation. Similar behavior has been observed InP- and InAs-based QCLs emitting near 8${\mu}$m. Numerical simulations performed using a model based rate equations excitation by current pulses non-zero rise provide fair agreement our observations.

متن کاملDesign Optimization for 4.1-THZ Quantum Cascade Lasers
We present an optimized design for GaAs/AlGaAs quantum cascade lasers operating at 4.1THz. This was based on a three-well active module with diagonal radiative transition. This was performed by modifying the existing model structure, to reduce the parasitic anticrossings (leakage currents) as well as the optical gain linewidth. While the gain FWHM was reduced by more than 50% the gain pea...
متن کاملLaser-assisted hair removal: comparison of long-pulsed alexandrite and long-pulsed Nd:YAG lasers, individually and in combination
Background and aim: Laser is one of the most recent techniques which has widespread use in the treatment of many skin diseases. This technique has been successfully used to remove unwanted hairs in hirsutism. The aim of this study was to evaluate and compare the efficacy and safety of long-pulsed 755 nm alexandrite and long-pulsed 1064 nm Nd: YAG lasers individually and in combination for perma...
متن کاملChemical Sensors Based on Quantum Cascade Lasers
There is an increasing need in many chemical sensing applications ranging from industrial process control to environmental science and medical diagnostics for fast, sensitive, and selective gas detection based on laser spectroscopy. The recent availability of novel pulsed and CW quantum cascade distributed feedback (QC-DFB) lasers as mid-infrared spectroscopic sources address this need. A numbe...
