WebMay 29, 2024 · However, gain narrowing significantly reduces bandwidth during the amplification process, and thus it is difficult to achieve a shorter pulse duration. Shorter pulse durations in CPA regenerative amplifiers have been demonstrated by reducing gain narrowing in two ways: intra-cavity and extra-cavity.

WebSep 15, 2024 · Both gain-narrowing and red-shifting effects can result in significant spectral distortion and correspondingly lengthening of the compressed pulse … WebJan 26, 2024 · In addition, the gain of the regenerative amplifier decreases more slowly in the longer-wavelength region than in shorter-wavelength region. These experimental measurements can be used to guide the seed laser design by matching the gain spectrum of the regenerative amplifier.
WebFor the most part, gain narrowing compensation has been investigated, and there are very few solutions proposed for the spectral shifting effect due to amplification saturation [13]. … WebOct 27, 2024 · Therefore, only the gain narrowing effect contributed to the spectral modulation in the subsequent fiber amplifiers. The average powers of the amplified signal pulses delivered by the subsequent fiber amplifiers were optimized to be 102.1 mW, 1.55 W, and 10.21 W, respectively. The spectral bandwidth was further decreased from 9.6 nm to …
WebOct 29, 1999 · Emission transients at the spectral position where gain-narrowing occurs (2.53 eV) for three different pump fluences on a logarithmic scale (dashed lines). The solid lines present single-exponential (1.5 μJ/cm 2 ) and double-exponential (5.0 and 7.5 μJ/cm 2 ) fits to the measured transients. WebLaser linewidth from high-power high-gain pulsed laser oscillators, comprising line narrowing optics, is a function of the geometrical and dispersive features of the laser cavity. To a first approximation the laser linewidth, in an optimized cavity, is directly proportional to the beam divergence of the emission multiplied by the inverse of the ...
