Abstract

The output spectral, temporal, and spatial parameters of a two-channel Yb-fiber laser operating in an incoherent intracavity spectral beam-combining mode were investigated. One of the laser channels operated in continuous pumping mode, and the second channel operated in pulse-periodic pumping mode with a pulse duration of microseconds. When the channels operated separately, continuous lasing at a wavelength of λ1 was observed in one channel, and pulsed lasing at a wavelength of λ2 was observed in the other. When both channels operated simultaneously, it was shown that during the pump pulse action, the laser switched operation to pulsed collective mode lasing at a wavelength of (λ1 + λ2)/2. Lasing at wavelengths λ1 and λ2 was not observed at this time.

带有腔内光谱光束组合的激光器，采用连续波和脉冲周期泵浦的各种激光通道

研究了以非相干腔内光谱合束模式运行的双通道掺镱光纤激光器的输出光谱、时间和空间参数。其中一个激光通道以连续泵浦模式工作，第二个通道以脉冲周期泵浦模式工作，脉冲持续时间为微秒。当两个通道分别工作时，一个通道观察到波长为 λ1 的连续激光，另一个通道观察到波长为 λ2 的脉冲激光。当两个通道同时工作时，结果表明在泵浦脉冲作用期间，激光器切换到波长为 (λ1 + λ2)/2 的脉冲集体模式激光。此时没有观察到波长为 λ1 和 λ2 的激光。

期刊介绍： Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
