Excellent beam quality
The beam quality of the end pump laser marking machine much better than traditional solid-state laser marking machine, the output of the fundamental mode, the focused spot diameter can reach 20um. The divergence angle is 1/4 of the semiconductor side of the pump laser. Particularly suitable for precise, fine marking.
Principle
With the major breakthrough of the semiconductor laser diode technology, solid state lasers has been the strong development of its applications continue to expand. One of the most important is the development of semiconductor lasers and semiconductor array laser-pumped solid state laser technology, which is a high efficiency, long life, high beam quality, good stability, compact miniaturized second-generation solid-state lasers , is continuous, non-linear conversion of the pulse, Q, as well as add octave mixers and so on. The pump coupling can be divided into end-pumped and side-pumped, end-pumped can be divided into direct end-pumped fiber-coupled end-pumped two structures. Compared side-pumped, end-pumped efficient. This is because, in the case of pump laser mode is not too bad, the pump light is coupled into the optical system of the working substance, less coupling loss. For example, we now see the use of end-pumped solid-state lasers pumped semiconductor coupling mode end-pumped YAG laser marking machine referred to as the end pump laser marking machine. The internal side pump laser using a semiconductor array as the pump source, injected from the end after fiber-coupled laser crystal. It is because of the high efficiency of end-pumped mode, pattern matching, wavelength matching the advantage of extremely rapid development in the international arena in recent years, has become one of the focus on the development direction of the laser disciplines. Its laser marking, laser micro-processing and other fields have a wide range of uses and has great market potential.
