Factors That Influence Peak Power of Q-Switched Fiber Laser

Abstract: Q-switched fiber lasers are very attractive sources in many applications such as military affairs, surgical operation, laser machining, laser marking, nonlinear frequency conversion, range finding, remote sensing and optical time domain reflectometer. To improve the peak power of Q-switched fiber laser is what we pursue, and to know the factors that influence the peak power is what we should make clear first. In this paper, certain essential factors that influence the peak power are presented, with their theor… Show more

“…54,57 Despite the inability to directly locate this dark state in absorption spectroscopy, several time-resolved studies have invoked non-adiabatic transitions involving it to explain the sub 200 fs dynamics observed in ion-and photoelectron signals subsequent to excitation to the bright (p,p * )-state. 23,58,59 The short timescales involved can also be inferred from the lack of detectable fluorescence of CPD, 60 further hinting at the involvement of a doubly excited state.…”

“…Numerous experimental studies have investigated the low-lying valence states in CPD [52][53][54][55][56][57] but only few have discussed the spectral position of the doubly excited state. 54,57 Despite the inability to directly locate this dark state in absorption spectroscopy, several time-resolved studies have invoked non-adiabatic transitions involving it to explain the sub 200 fs dynamics observed in ion-and photoelectron signals subsequent to excitation to the bright (p,p * )-state. 23,58,59 The short timescales involved can also be inferred from the lack of detectable fluorescence of CPD, 60 further hinting at the involvement of a doubly excited state.…”

“…Even when the molecules are oriented isotropically relative to the polarization of the exciting laser, the polarization properties of the scattered light are sensitive to the relative orientations of the molecular transition dipole moments if more than one transition contributes. Depolarization ratios in resonance Raman scattering have long been exploited to extract information about overlapping electronic transitions 26, 53–57, and the extension to resonance hyper‐Raman and hyper‐Rayleigh scattering presents some new opportunities. Of particular interest are molecules that consist of more than one nominally identical chromophore, such as those shown in Figures 12 and 13.…”
