Abstract

Several evidences, typical of a superfluorescence effect, have been obtained for the first time under continuous excitation. Emission from Er 3+ in LiYF 4 at 10 K is obtained at 2.72 μm with a threshold of ≃ 3 mW of absorbed power at 6470 Å.

Solid-State Continuous Superradiant Laser with a Wavelength in the Telecommunication Range

K. I. Gerasimov, Mansur M. Minnegaliev, Sergey A. Moiseev

Superradiance or superfluorescence properties are typically studied under pulsed excitation. In this work, superradiance lasing under continuous pumping without a special external cavity has been studied. Lasing has been achieved in a YPO 4 :Er 3+ solid with a narrow emission line (~48 kHz), in single-mode, single-frequency operation, with a high quantum differential efficiency (~84%), a low lasing threshold, and at a telecommunication wavelength (~1.5 μm).

CW lasing in Yb3+: GGG crystals pumped at 0.925 μm

A M Belovolov, Mikhail I. Belovolov, Evgenii M Dianov +2 more

Single-mode cw lasing was obtained for the first time in Yb 3+ : GGG crystals at room temperature at 1.030 and 1.037 μm upon pumping Yb 3+ ions by a 0.925-μm neodymium-doped fibre laser. Lasing was observed at the transitions between the lower Stark sublevel of the 2 F 5/2 level and the upper Stark sublevels of the 2 F 7/2 ground state of Yb 3+ ions. The study of lasing characteristic showed that lasing occurs according to the four-level scheme. The lasing threshold with respect to the absorbed power was 85 mW and the slope lasing efficiency was 20%. Upon 1.7-W pumping, the output power of 310 mW was achieved with the output resonator mirror with the transmission coefficient of 1%. The effective cross section of the lasing transition was 0.9 × 10 -20 cm 2 .

Continuous-wave mirrorless lasing at 221 μm in sodium vapors

A. M. Akulshin, Felipe Pedreros Bustos, Dmitry Budker

We demonstrate backward-directed continuous-wave (cw) emission at 2.21 {\mu}m generated on the 4P3/2-4S1/2 population-inverted transition in Na vapors two-photon excited with resonant laser light at 589 and 569 nm. Our study of power and atom-number-density threshold characteristics shows that lasing occurs at sub-10 mW total power of the applied laser light. The observed 6 mrad divergence is defined mainly by the aspect ratio of the gain region. We find that mirrorless lasing at 2.21 {\mu}m is magnetic field and polarization dependent that may be useful for remote magnetometry. The presented results could help determine the requirements for obtaining directional return from sodium atoms in the mesosphere
