LASER EXCITATION IN A GaAs ANODE i>43 Calculations of Laser Excitation in a GaAs Anode by Slow Electrons
The laser mechanism in a p-type GaAs slab with no junction and a hole concentration higher than 7 x 1018 cm3 is investigated theoretically for the case that the excited electrons are injected from a gas discharge outside the slab. With such an excitation by slow electrons a lower bound of the current density is calculated from the S c h a w lo w —T o w n e s condition. The losses of diffraction...
متن کاملOn the performance conditions of a N2 laser
2014 The peak power and the actual starting voltage of the N2 laser light pulses there have been studied, in relation to the pressure and the pulse repetition rate. The experimental results reveal that under proper conditions of pressure and pulse repetition rate, high peak power pulses are emitted. By comparing the theoretical and experimental results, there have been given explanations as far...
متن کاملModeling of a Pulsed C0/n2 Molecular Laser System
A detailed numerical model has been developed for characterizing the important energy transfer processes operative in the CO/ft, direct current discharge laser system. The model is based upon a rate equation formulation which includes 30 levels of both CO and N_ and treats multi-quantum electron-molecule excitation processes, single quantum vibration-vibration exchange and vibrationtranslation ...
متن کاملStudy of Geometrical-Dependence of Glow Discharge on Gain Coefficient in a TE-N2 Laser
Based on a set of experiments, using a transversely exited (TE) oscillator-amplifier N2-laser system (OSC-AMP) with the AMP effective length of 31cm, measurements have been carried out for small signal gain, g0, and saturation energy density, Es, for different AMP gap separations. It was found that the gain-value depends on the AMP electrode gap separation, d<su...

embryos with nuclei from human cells inserted into the eggs of either cows, pigs, sheep or other animals. When the issue was debated in Parliament, many leading scientists strongly supported such research. “Animal–human hybrid embryo research needs legal permission, good scientists and more funding,” says Evan Harris, the science spokesman for the Liberal Democrat Party. Many of those involved ...
