The diode end-pumped Q-switched laser marking machine is an air-cooled small compact and low power consumption. The laser beam has TEMoo with high beam quality high peak power and short pulse width.
To meet the growing demand for industrial precision processing, we have creatively developed the diode end-pumped Q-switched UV laser marking machine. It is small, compact and low power consumption. This laser machine can meet the requirements of most industrial precision processing.

Marking field: Marking field depends on scan lens (f-theta lens) once other parameters and parts are confirmed. Large field sizes demand the use of lenses of long focal length. In turn, this leads to increase focused spot size and decrease laser power density on the workpiece. Thus reasonable mark field should be carefully selected. If both small focused beam diameter (narrow line width) and large marking field are simultaneously required, a XY moving table is recommended for best performance. However, there may be a little alignment along the junction edges of neighbour pisions since the moving accuracy and resolution are always limited.
Focused beam diameter: The focused beam diameter is related to f-theta lens, beam expander and laser parameter (beam quality, beam diameter, beam pergence etc). Higher laser power always needs larger beam diameter and thus results in worse beam quality (such as larger pergence angle etc) and further results in larger focused beam diameter.
Mark linewidth: in order to get narrow linewidth, 1) you may use the f-theta lens with smaller mark field and beam expander with larger beam expansion ratio. 2) You may increase beam quality by inserting an aperture inside laser resonator. 3) you may increase the marking speed.
