Who doesn't love a humongous laser? Here at ExtremeTech, we're fans of both 1) technology and 2) extremes, and lasers are toward the far end of both spectra. So, do you have a minute? In the spirit of ...

A Massachusetts university is developing technology that aims to use lasers to drastically cut emissions and energy use from Maine’s paper and pulp industry. Worcester Polytechnic Institute recently ...

Fabric must be cut before it can be turned into something else, and [fiercekittenz] shows how a laser cutter can hit all the right bases to save a lot of time on the process. She demonstrates ...

Cutting grass with lasers works great in a test setup. (Credit: Allen Pan, YouTube) Wouldn’t it be cool if you could cut the grass with lasers? Everyone knows that lasers are basically magic, and if ...

Oil prices are spiking again, this time because of the war unfolding in the Middle East. What would happen, however, if we could end our reliance on oil for good? People have been ...

Ferda Canbaz demonstrates the depth of cuts that can be achieved with lasers when the energy profile of the laser beam is adjusted. Lasers cut precisely and without contact – ideal for surgery. The ...

The International Day of Light is held on May 16th every year, a date that marks the anniversary of the first successful operation of the laser by Theodore Maiman in 1960. This pivotal moment changed ...

Lasers cut precisely and without contact – ideal for surgery. The problem is that, in hard tissues such as bone, they are too slow and do not cut deep enough. Researchers at the University of Basel ...

There are many different types of lasers—almost as many as there are applications for the same—but what ties them all together as a class is that they depend on the same physical effect: stimulated ...
