The idea of cooling a solid-state optical material by simply shining a laser beam onto it may seem counterintuitive, but this is rapidly becoming a promising technology for future cryocoolers.

Most laser cleaning setups use scanning optics. These move the beam at multiple meters per second to project a desired shape, such as a circle or rectangle, onto the surface. But what is laser ...

If shaving is growing tiresome, consider laser hair removal: This method damages hair follicles to reduce growth over time, ultimately giving more long-term results than using a razor. After ...
