WebWhen laser action is taking place, this self-limiting effect is no longer operating. Because of the possibility of longer path lengths through the plasma, the larger the volume of active lasing medium, the greater the gain. In the laser, stimulated emission from a population inversion creates a negative optical thickness. WebSep 4, 2012 · The laser system consists of 532 nm output from an injection-seeded Spectra Physics PRO-290-10 Nd:YAG laser, which pumps a Sirah Cobra Stretch pulsed dye laser …
WebWe present a detailed theoretical study of a recent experiment [A. J. Traverso et al., Proc. Natl. Acad. Sci. USA 109, 15185 (2012)] in which a laserlike source is created in air by pumping with a nanosecond pulse. The source generates radiation in WebThis work is focused on quantum coherence and superradiant emission in a dense pencil-like multi-level medium where many novel e ects appear such as transient lasing without inversion, coherence-brightened sky laser, and quantum ampli cation by superradiant emission of radiation. We start from an interesting cascade model where quantum ...

This is a direct application of Dicke’s “coherence-brightened laser” proposal. Keywords. Output Coupler; Round Trip Time; Gain Medium; Streak Camera; Dephasing Time
Web2 lasers and the exploration of coherent brightened laser sources in air. It deserves mentioning that the role of rotational coherence discussed herein is distinguished from the macroscopic molecular alignment effect [8,27–30], which can merely modulate lasing gain at alignment delays. The nonzero value of rotational coherence in the vibrational
