Mode-locked single-mode fiber lasers offer advantages due to their high-gain doping, intrinsically single-spatial mode, and compact setups. However, in terms of power levels, mode-locked fiber lasers suffer from high nonlinearity, which is introduced by the small core size of the single-mode fibers. Researchers from \u00c9cole Polytechnique F\u00e9d\u00e9rale de Lausanne, Switzerland (EPFL) recently developed a new approach for generating high-energy, ultrashort pulses with single-mode beam quality: nonlinear beam cleaning in a multimode laser cavity.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2020-12-nonlinear-spatiotemporally-mode-locked-lasers.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Nonlinear beam cleaning in spatiotemporally mode-locked lasers<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In the last few decades, only temporal modes have been considered for mode-locked fiber lasers using single-mode fibers.
