For
example, for material thicker than 10 gauge, tests have shown that
nitrogen produces faster cuts, but in the mild steel range of 10 gauge
(0.135 inch) and thinner, air is roughly 3 percent faster than nitrogen.
In the stainless steel range from 0.750 in. down to 20 gauge (0.036
in.), air is about 22 percent faster. In the aluminum range from 0.190
in. down to 0.032 in., air is approximately 14 percent faster.

At
Photonics West in 2019, Laserline presented results on fiber-coupling
of two stacks of GaN diode bars, reaching 1000 W of power at 450
nm with 25% electro-optical
efficiency. BlauLas had increased the output power of a blue direct
diode laser by an order of magnitude. Shortly thereafter, Osram launched
a commercial laser bar chip with 50 W of 445-nm optical power, 7.5%
fill factor and a 38% conversion efficiency. |

Overall efficiency of CO2
lasers ranges from about 5% to 20%, and output power, depending on the
design, can be as low as hundreds of milliwatts or as high as hundreds
of kilowatts. |

Ozone is produced from oxygen. Oxygen is
present in our ambient air at a level of about 20%. Using air to produce
ozone will work and will produce ozone from the oxygen in ambient air.
However, if a higher concentration of oxygen is used, more ozone will be
produced. Many ozone generators will implement an oxygen concentrator to increase oxygen levels in the feed gas and increase overall ozone production. |
