(PhysOrg.com) -- Random lasing, Robin Kaiser tells PhysOrg.com, is like standard lasing, with a little bit of a twist: “You don’t know the direction the photons will go, as you do with a more standard laser. This is because ...
An optical isolator developed at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) could drastically improve optical systems for many practical applications.
