Single transverse mode is the one that gives the smallest focal point. 5 mm, single-pass linewidth was estimated to be 1. 55 μm ridge guide C3 laser,” Electron. These lasers have long coherence length and narrow spectrum linewidth, they are ideal for holography etc. The PLM series are power stabilised laser sources in a compact and rugged enclosure ideally suited for applications demanding stable and high power multimode Single-longitudinal-mode operation of injection laser coupled to a GRINROD external cavity Liou, K. By means of linear resonator stable redlight pulses were obtained at 660 nm having Emax = 5mJ output energy and τ = 50 ns (FWHM) Abstract. Pub Date: 1983 DOI Laser Dynamics (single-mode) Before we start to look into the dynamics of a multi-mode laser, we should recall the technically important regimes of operation of a ”single-mode” laser. Applications. single longitudinal mode lasers
