We measured the lifetime of the B2Σ+, v = 0 level of the astrophysically important CO+ molecule by applying the collinear beam-laser method. Ions in the long-lived A2Π level were excited to the B2Σ+ state by a single-frequency laser beam in resonance with a transition in the B2Σ+ – A2Π Baldet–Johnson band, and the laser-induced fluorescence from the B2Σ+ – X2Σ+ First Negative band was monitored as a function of distance from the excitation region. We claim that our result of 54.9 ± 0.7 ns is less likely to have suffered from systematic error than previous measurements, which were mutually discordant. PACS No. 33.70Ca

In recent years, the transition metal carbonitrides(MXenes) have been widely applied to photoelectric field, and better performance of these applications was achieved via MXene complex structures. In our work, we proposed a MXene core-shell nanosheet composed of a Ti2C (MXene) phase and gold nanoparticles, and applied it to mode-locked and single-frequency fiber laser applications. The optoelectronic results suggested that the performances of these two applications were both improved when MXene core-shell nanosheets were applied. As a result, we obtained a mode-locking operation with 670 fs pulses, and the threshold pump power reached to as low as 20 mW. Besides, a single-frequency laser with the narrowest linewidth of ~1 kHz is also demonstrated experimentally. Our research work proved that MXene core-shell nanosheets could be used as saturable absorbers (SAs) to promote versatile photonic applications.
