Abstract
A device and method for resonant pumping of optical gain medium, comprising an electrical pump, an ultracoherent microlaser, and a plasma microresonator. The ultracoherent microlaser can comprise an orthogonal laser supported by a whispering-gallery disk resonator. The electrical pump can electrically pump plasma to trigger a semiconductor laser with 1 centimeter coherence to orthogonally resonantly enhance an ultracoherent laser. For a disk thickness near 1 micron, a factor of 20,000× in resonantly enhancing pump efficiency is achievable. The plasma microresonator can also comprise microbubble cavities, argon plasma, and walls thinner than an optical wavelength.
