Continuous-wave spontaneous lasing in mercury pumped by resonant two-photon absorption
Daniel Kolbe, Martin Scheid, Andreas Koglbauer +1
The first continuous-wave two-photon absorption laser-induced stimulated emission (CTALISE) is demonstrated. The 7^1S-6^1P transition in mercury at 1014nm wavelength is used and se…
