The new method is far more expensive, but it allowed scientists to use a laser beam to control lightning bolts. The physicists working on the experiment did so from a mountaintop in Switzerland ...

But a fiber laser with 200kW peak power is in another hazard class entirely ... doped fiber of the two-stage amplifier, which is the active gain medium where stimulated emission, and therefore ...

Researchers at Nichia Corporation have demonstrated green InGaN-based lasers grown on c-plane ... with a 5-mW output power under automatic power control. Using the customary definition of lifetime ...

Their study is published in the journal Laser and Photonics Reviews ... in large sizes and with sophisticated, high-power electrical and control systems. And each is geared towards operation ...

With laser diodes, the larger the surface of the active material producing the laser light, known as a resonator, the greater the output power. But increasing the area of the resonator also ...

In the video after the break, [Eric Strebel] goes through them all and pits each one against his 50 W water-cooled laser with air assist ... the optimum speed and power settings for each of ...
