Web4. jún 1998 · The laser operates in the fundamental mode up to 0.7 mW with 3.2 mW total peak optical output power. Direct evidence of spatial hole burning for the fundamental and the next higher mode is observed. This spatial hole burning puts a limit on the fundamental mode operation and efficiency of the lasers. Web1. júl 1993 · We observe, that the spatial hole burning effect affects relaxation oscillation parameters ~ and SZ with different strength for different values of the reflectivity phase fp. Additionally, this effect is different in the planar and fiber laser structure. For the fiber laser structure the acting strength of the SHB effect on the relaxation ...
Research on spatial hole burning effect of linear cavity fiber laser
WebSPATIAL HOLE BURNING: Spatial hole burning is responsible in gain suppression in a laser cavity. This phenomenon appears naturally in the semiclassical theory of laser. This hole … Web1. júl 1993 · It is shown that in general the spatial hole burning effect increases the damping rate and the frequency of the relaxation oscillations. Moreover, this effect affects laser characteristics stronger in the fiber structure. References (9) S.R. Chinn. Appl. Optics (1976) P. Szczepański et al. J. Lightwave Techn. (1992) M.

WebWe measure spatial hole burning in weakly index guided vertical‐cavity surface‐emitting laser diodes (VCSELs) by spatially and spectrally resolving the spontaneous emission near field above threshold and show that spatial holes produce a significant lensing effect. We demonstrate experimentally, and with a simple model, that … Web12. mar 2024 · Linear cavity optical fiber lasers have the advantages of small size, light weight, stable mode, and easy large-scale multiplexing. However, due to the spatial hole burning effect in linear cavity lasers, the long linear cavity fiber lasers have the problem of multi-mode oscillation. In this paper, the quarter-wave plate made by polarization ... http://archive.nstl.gov.cn/Archives/browse.do?action=viewDetail&articleID=d05d745ee8251c19&navig=9565bcbb40dbfbe9&navigator=category&flag=byWord&subjectCode=null&searchfrom=null property custodian
