Continuous-wave spontaneous lasing in mercury pumped by resonant two-photon absorption.
We demonstrate the first cw two-photon absorption laser-induced stimulated emission. The 7(1)S(0)-6(1)P(1) transition in mercury at a 1014 nm wavelength is used, and selective lasing of different isotopes is observed.
