Abstract:Thus, the energy transfer to a new spectral band in the short random fiber laser is accompanied with the increase of the photon number by several percent NS out / NP out = 1.03.3 With shorter fiber length, the optical conversion efficiency could approach quantum limit (defined as hyS/hyP), and the power scaling of the laser can also be dramatically increased, due to the much higher threshold of the second-order random lasing.4 An even shorter cavity of 300 m helped to achieve a 73.7 W output, with a Gaussian profile in the fundamental transverse mode.5 The random fiber laser offers greater ...
