“…Introduction.-Magnetic dipole transitions are usually several orders of magnitude weaker than electric dipole transitions [1], yet they are technologically very relevant, for example in Lanthanoide-ion-doped lasing media [2]. However, the radiative properties of photon emitters highly depend on their photonic environment, i.e., on the local density of states (LDOS), which was first analyzed by Purcell [3].…”

We numerically explore the emission behavior of magnetic dipole emitters located next to resonant plasmonic split-ring resonators (SRRs), which are well known for their large magnetic moment at their fundamental resonance in the near infrared. Our results are compared to the situation for electric dipole emitters, where the SRR can be described by solely its electric dipole moment. We show that a similar approach in the case of magnetic dipole emitters is not sufficient, as the symmetry breaking due to the gap has to be taken into account. We demonstrate how retardation between the emitter and the SRR can be used as an additional degree of freedom to manipulate the emission spectrum. Our concept will pave the road towards efficient plasmonic antennas for magnetic dipole emitters.

“…A 10 m length of Yb:Er-doped double-clad silica fibre (INO, Canada) was used, having an inner cladding of 200 mm distance between parallel planes of a hexagonal geometry, with a silicone outer The measured Yb:Er-silica fibre laser output is around 1.61 mm, with FWHM $2-3 nm as shown in figure 3. It is believed that 1.61 mm is near the longest lasing wavelength that can achieve significant output from the Er-doped fibre laser [8][9][10][11].…”

In-band pumping of multi-mode Tm-silica fibre lasers operating at 2 mm has strong potential due to higher quantum efficiency, increased damage threshold, increased nonlinear threshold and practical larger pumping area. Results are presented on the investigation of multi-mode Tm-silica fibre lasers operating near 1.85 mm, containing a high Tm doping concentration of 1.1 wt% (9 Â 10 25 m À3 ), when in-band pumped at 1.61 mm near an absorption peak in Tm-silica. The relationships between lasing performance and fibre length and cavity losses are reported. The measured highest slope efficiency and threshold achieved are about 42% and 0.4 W obtained with a short optimum fibre length of 23 cm and cavity reflectivities of (99%-4%), and on a small scale in this configuration a maximum output power of 370 mW was produced. The estimated maximum slope efficiency for the cavity reflectivities of (4%-4%) is up to 56%.

“…At longer wavelengths, transitions terminate at a partially thermally populated level above the ground state such that the medium behaves like a quasi-four-level system, with the inherent loss decreasing as the wavelength increases. This behavior has been used to achieve lasing in longer E?+-doped fibers at wavelengths as high as 1.65 pm [34].…”

I Abstract-Data are presented on Er3+-doped superfluoresent fiber sources showing the dependence of output characteristics on pump wavelength and power, fiber length, fiber temperature, and feedback. In particular, the broadband operation and mean wavelength stability required for fiber optic gyroscope applications are evaluated. Substantial improvements in the mean wavelength stability with pump power have been achieved by optimizing the fiber length. An all-fiber superfluorescent fiber source utilizing a fiber-pigtailed 980-nm diode pump laser is demonstrated, with a 1-h mean wavelength stability better than 0.9 pprn RMS and 58 ppm drift over 20 h. The intrinsic mean wavelength variation versus fiber temperature is measured, with values of 4.8 and 3.0 ppmPC obtained for fiber lengths of 23 and 78 m, respectively.
