a laser beam—can block another beam, forming a visible shadow. “Our demonstration of a very counter-intuitive optical effect invites us to reconsider our notion of shadow,” Abrahao explains.

The effect occurs because the green laser increases the optical absorption of the blue illuminating laser beam, creating a matching region in the illuminating light with lower optical intensity.

Caltech researchers develop a platform to characterize ultrathin membranes for lightsails, advancing the quest for ...

Fractional CO 2 lasers minimize the risk of adverse effects due to the targeted nature of the laser beam columns. This form of laser treatment also has a faster recovery time. A 2017 review ...
