New laser technology could improve how scientists study molecules
We use lasers for a lot of things , from cutting metal to improving eyesight, but lasers have their limitations. One major holdup is that they can only emit certain types of light. Researchers have gotten around this particular limitation by using what are known as optical parametric oscillators, which allow regular laser light to be converted into other wavelengths of light that may be useful for certain areas of research. One example is studying how molecules behave. However, these gadgets have their limitations too. They typically have weak outputs and they require extreme stability and precision, making them hard to use outside of highly controlled lab environments. But researchers at Stanford may have found a way around this issue and their work could make these systems more efficient and easier to use. Here's how these oscillators work. Laser light is filtered through a crystal, which converts that light into those other wavelengths that researchers need. That light is th...
