A ‘ready-to-use’ Pulsed Yb-Fiber laser module has been developed. M/s Spinks Impex, Gurugram, completed thorough performance evaluation of 20W pulsed fiber laser module by synchronizing their existing marking system with the indigenously developed electronic Interfacing- protocol of the laser module. The trial was conducted at CSIR-CGCRI in the presence of the technical team from M/s Spinks Impex. The stability of the Yb-Fiber laser was tested for extended hours while the marking was going on. Marking was done on various materials with uniformity under conditions of non-condensing humidity.
