Description

Technical Field

[0001] The present invention relates to the technical field of pulse lasers, in particular to a high-power 976nm DFB pulse laser. Background Art

[0002] Lasers are divided into continuous lasers and pulsed lasers based on their operation. Pulsed lasers refer to lasers with a single laser pulse width of less than 0.25 seconds and only work once every certain interval. They have a large output power and are suitable for laser marking, cutting, ranging, etc.

[0003] A DFB laser, or distributed feedback laser, incorporates a Bragg grating structure. When current is injected into the active region, electrons and holes recombine to emit photons. These photons are reflected by the grating structure on the surface of the active layer, resulting in stimulated emission and, in turn, laser output. Pulsed output is achieved primarily through external modulation or specialized internal design techniques, such as Q-switching and mode-locking, which periodically alter cavity losses or phase to achieve pulsed laser output.
