1. High Power Blue Lasers AO-150
The 450 nm laser AO-150 is an air-cooled diode laser with 150 W output power in an SMA fiber connector with a 200 ?m core diameter. This power is available for cw operation or modulated with up to 50 kHz.
2. Characteristics of blue AO-150 lasers
This new generation of blue diode lasers has been developed for the micro- and macromaterial processing of copper, its alloys and precious metals. There are a number of highly reflective metals with limited absorption in the IR range, or even in the green range, where the blue laser radiation has significant advantages, especially in welding.
In the microscopic as well as the macroscopic observation of the welding process, the homogeneous course of the liquid phase of the welding is more reminiscent of a soft flow of wax than the known welding of metals.
A spatter-free machining process is characteristic for all types of welding. This applies in the case of actual welding, as well as in the case of application welding and drilling, even at a power output of 150 W.
