An oscillator amplifier nitrogen laser arrangement has been built. A small signal gain up to 340 dB/m was measured. Furthermore, image amplification of 170 times was demonstrated.doi:10.1515/zna-1972-1023Jörg StrübingFreie Universität Berlin, Institut für Soziologie, Babelsberger Straße ...
What is a nitrogen laser? What is a CW laser diode? What is a fiber laser marking machine? What is a 2D fiber laser cutting machine? What is an argon laser treatment of the retina? What are gas lasers used for? What is a single mode laser diode?
- 《Laser & Particle Beams》 被引量: 10发表: 1993年 Optimization of nitrogen filled capillary pinch for soft x-ray laser recombination pumping We report new results of evaluated gain for 13.38 nm radiation created due to the inversion population on the Balmer alpha transition of hydrogen-like ...
By calculations in the framework of the valence force field method, we show that nitrogen atoms in dilutedGaAs1xNxtend to align along the [001] direction. In quaternary alloysGa1yInyAs1xNxthis tendency is observed only in "as-grown" samples, while in the annealed samples nitrogen atoms build...
A simple method of reducing the divergence of high gain lasers by placing an anamorphic prism beam expander in the cavity is described. Using a nitrogen laser a 37-fold decrease in divergence and 9-fold increase in brightness were achieved. The method can be used in excimer and copper vapour...
Mice euthanasia was performed by carbon dioxide inhalation followed by decapitation. Forebrain samples (single hemisphere) and gastrocnemius muscle were collected in and flash frozen in liquid nitrogen and kept at − 80 ℃ until use. Total RNA was extracted using TRIzol (Invitrogen). RNA was...
摘要: GaAs QWs. Considering a possible blue shift of QW emission upon annealing (i.e., the post grown procedure, which is usually used for improving optical quality of these QWs) the required nitrogen concentration can be larger by ~0.5% N than the one calculated for as-grown QWs....
To demonstrate laser operation, Dneprovskii et al. deposited dielectric coatings with reflection coefficients of 95% and 100% on the parallel faces of a CdSe-doped glass plate [234]. The so obtained 1-nm-thick Fabry-Perot resonator was cooled to liquid nitrogen temperature. At low excitation ...
Molecular chaperones are essential cellular components that aid in protein folding and preventing the abnormal aggregation of disease-associated proteins. Mutations in one such chaperone, DNAJB6, were identified in patients with LGMDD1, a dominant autoso
Recently, there has been an emerging interest in using the AlInN alloy as the active region for deep UV laser diodes (λ ~ 250 nm)28, attributed to the full band gap coverage of the material in the UV spectrum. However, the literature on AlInN QW as the active region for deep UV...
