Brilliance
DIAMOND K-Series and G-Series lasers feature Brilliance™, a combination
of mode quality, peak power, and optical rise-and-fall times. With Brilliance,
DIAMOND lasers perform the same tasks as lasers whose continuous-wave (CW)
output power is two to three times greater. Brilliance also allows faster and
cleaner materials processing than lasers of comparable power.
The first characteristic of Brilliance is mode quality. The better a beam’s mode
quality, the smaller its focused spot. A smaller focused spot results in faster and
cleaner processing.
The instantaneous power of a laser pulse is the second characteristic of
Brilliance. A DIAMOND laser whose average output power is 500W has a peak
power of over 1.5 kW. The result is faster ablation of materials.
Third, superior optical rise-and-fall times measure how quickly the laser’s optical
pulse reaches full power and then shuts-off. Short rise-and-fall times create a
square-wave pulse profile that generates a smaller heat-affected zone (HAZ) in
the processed material.
DIAMOND lasers with Brilliance process materials cleaner and more efficiently
than any other commercial CO2 laser.
