Abstract

Provided are a laser (100) and a laser generation method, relating to the technical field of photoelectricity. The laser (100) comprises: a controller (120), M paths of light source modules (130) connected to the controller (120), and a beam combiner (140) connected to the M paths of light source modules (130), wherein M is an integer greater than one. The controller (120) is used for sending a corresponding pulse control signal set to each path of light source module (130) of the M paths of light source modules (130); each path of light source module (130) is used for outputting one path of laser pulse according to the corresponding pulse control signal set, and the M paths of light source modules (130) output M paths of laser pulses in total; and the beam combiner (140) is used for synthesizing the received M paths of laser pulses, and acquiring and outputting one path of output laser pulse which meets preset requirements. By using the corresponding combination method for M pulses, the capacity of the output laser pulse can be the sum of the energy of M pulses, and the energy, the average power and the duration of the output laser pulse are greatly increased, so that the output laser pulse can meet the usage requirements.

Description

technical field [0001] The present application relates to the field of optoelectronic technology, in particular, to a laser and a laser generating method. Background technique [0002] Due to its high flexibility, maintenance-free, low energy consumption, high beam quality and other advantages, pulsed fiber lasers are widely used in material surface processing, thin metal cutting / welding and other applications. [0003] At present, the average power of pulsed fiber laser can reach 100-500W, the pulse energy can reach 1-10mJ, and the pulse width can reach 100-500ns. However, with the development of industry technology, pulsed fiber lasers need to provide greater average power, greater pulse energy, and longer pulse width to meet higher requirements. The average power, pulse energy and pulse width of current pulsed fiber lasers are gradually unable to meet the needs of use. Contents of the invention [0004] The present application aims to provide a laser and a laser gener...
