But boosting power usually means decreasing beam quality or focus. And the beam never gets intense enough to melt metal.
Now MIT Lincoln Laboratory spinout Teradiode is commercializing a multikilowatt diode laser system that s bright enough to cut
The 4-kilowatt Terablade runs on a novel power-scaling technique developed at MIT that manipulates individual diode laser beams into a single output ray.
This allows for boosting power of a diode laser while preserving a very focused beam. The Terablade has comparable beam quality as compared with traditional manufacturing lasers such as carbon dioxide disk
and fiber says Teradiode cofounder and vice president Robin Huang a former Lincoln Laboratory researcher and Terablade co-inventor.
or incoherent beam combining developed by Huang and former Lincoln Laboratory researcher and Teradiode cofounder Bien Chann who is now the company s vice president and chief technology officer.
An individual diode laser in say a laser pointer can emit a beam in infrared and near-infrared wavelengths that can be focused tightly to a very small spot
Overlapping many similar beams at differing wavelengths however produces a beam that focuses on a small spot making it very intense.
And the number of overlapping beams with differing wavelengths can be very high. In the early 2000s Huang Chann and Lincoln Laboratory colleagues built a few prototype lasers based on WBC technology.
One which reached a power level of 50 watts was a world s record for diode laser brightness at that time Huang says.
which it s designed to do the grating forces the beams into the same direction superimposing them on one another.
or spatial beam combining that joins together the beams of similar wavelengths. As the number of diode lasers increases the beam quality degrades resulting in a large focused spot limiting the beam s intensity.
This means the Terablade outputs a beam roughly 100 times brighter than these scaled-up direct-diode laser models Huang says.
Each Terablade module outputs about 1000 watts and can be scaled to increase power. The company has developed also a commercial Terablade system:

Under a strong electric field the cathode emits tight high-speed beams of electrons through its sharp nanotube tips a phenomenon called field emission.

This way the system can turn off some beams sometimes without the driver noticing too much. To make raindrops disappear the system tracks falling rain predicts where the drops are going
