Diode laser dual-end-surface-pumped dual-output all-solid-state laser

Abstract

Disclosed is a diode laser dual-end-surface-pumped dual-output all-solid-state laser. The all-solid-state laser mainly solves the problem that an existing diode laser end-surface-pumped all-solid-state laser applied in a laser marking system leads to laser energy loss, causes bad laser output facular mode and ineffective beam splitting effect after employing an optical splitter to split beams. The all-solid-state laser is characterized by further comprising a dichroscope capable of performing 808 nm pumping anti-reflection with double sides when at 45-degree angle; one side of the dichroscopeclose to a laser crystal can perform 1064 nm resonant optical total refection; the all-solid-state laser comprises two exactly identical diode laser modules, two groups of coupling optical fibers, two optical focusing systems, two dichroscopes in 45-degree angle arrangement, two laser crystals and two output coupling mirrors which are all in sequentially parallel and symmetric arrangement inside the all-solid-state laser to form a U-shaped resonant cavity. The all-solid-state laser has the advantages of lessening laser energy loss and having good beam splitting effect.

Description

Technical field: [0001] The invention belongs to the application field of laser technology, and in particular relates to a diode laser end-pumped all-solid-state laser used in a laser marking system. Background technique: [0002] Since the 1990s, with the development of diode laser end-pumped all-solid-state lasers, traditional solid-state lasers have been gradually replaced in various application fields, such as applications in laser marking systems. However, after a long period of application, it was found that the diode laser end-pumped all-solid-state laser currently used in the laser marking system has the following problems: that is, when it is necessary to mark two products at the same time at the same time, in order to reduce costs and improve In order to improve efficiency, users often have to install two sets of scanning focusing lenses on a diode laser end-pumped all-solid-state laser to achieve the goal. Correspondingly, for lasers, an optical beam splitter mus...
