Blue DDL

Panasonic’s patented Wavelength Beam Combining (WBC) technology produces blue direct diode lasers with the high power and superior beam quality. Panasonic’s blue laser has unmatched performance in welding, cutting, and marking of highly reflective materials such as copper. Blue WBC technology simplifies manufacturing processes by delivering wider process windows, minimizing weld spatter, and increasing processing speeds.


Blue light is better absorbed by metals


Efficient absorption means less heat affected zone to achieve the desired result thereby reducing the potential for mechanical distortion of parts due to excessive heat input.


WBC (Wavelength Beam Combining)

From Whitelight to Rainbow

As white light passes through a prism it is diffracted into the various colors of the spectrum. WBC applies this familiar concept to laser diodes but in reverse.



Each of the many hundreds of laser diode emitters in our resonator produces a unique wavelength (color). Each of these unique beams is directed through a diffractive optic and combined with extreme precision to produce a laser beam hundreds of times brighter all while preserving the beam quality of a single emitter


BlueDDL Sample

2 stacked copper plates welding

High absorption of blue light means copper can be welded almost free of spatter with minimal heat input

High beam quality provided by WBC technology enables microfabrication. Line size is 70 μm

What’s DDL (Direct Diode Laser)?

What Makes Panasonic Direct Diode Laser (DDL) Special?

Our direct diode laser is applicable not only to the metal cutting and welding, but also to the next generation thermal processing fields such as 3D printing, surface processing, and multi material processing for nonferrous metals; all of which are expected to grow.
