Basic principle of Laser weeding

 

Laser weeding is a physical targeted weeding method that irradiates weeds with laser light to dehydrate, rupture and die the internal cells of the grass leaves. 

Selection of laser light source According to the characteristics of grass plants, there are currently two mainstream optional light sources for laser weeding 

Pulsed CO2 laser Wavelength: 10600nm, good non-metal absorption, easy to form thermal effect Optional power range: 30W/60W/150W/200W 

2) Continuous fiber laser Wavelength: 1064nm, concentrated heat, large thermal effect Optional power range: 300W/500W/1000W
