“…The stimulated emission cross section σ se ∼ 3.22 × 10 −21 m 2 for our sample is obtained in a similar fashion to the study by Fraczek et al [29], but considering only the NV − centres (see Appendix B). The value we obtain for our system is comparable to the values obtained in the literature previously [19,29,30]. Near our working wavelength of 721 nm, the study by Fraczek et al [29] specifies a ratio between the stimulated emission cross section of NV − and NV 0 of slightly higher than 3.…”

“…An NV − laser bypasses the shot noise problem since the detection of spontaneous photons is replaced by the detection of a weak coherent laser beam. The idea of using colour centres in diamond (and in particular, NV − centres) as a laser gain medium has been around for a while [17][18][19]. To the best of our knowledge, the demonstration of an NV − laser or even the stimulated emission of NV − centres inside an optical cavity has not been achieved so far.…”

Amplification by stimulated emission of nitrogen-vacancy centres in a diamond-loaded fibre cavity

et al. 2020

Laser threshold magnetometry using the negatively charged nitrogen-vacancy (NV−) centre in diamond as a gain medium has been proposed as a technique to dramatically enhance the sensitivity of room-temperature magnetometry. We experimentally explore a diamond-loaded open tunable fibre-cavity system as a potential contender for the realisation of lasing with NV− centres. We observe amplification of the transmission of a cavity-resonant seed laser at 721 nm when the cavity is pumped at 532 nm and attribute this to stimulated emission. Changes in the intensity of spontaneously emitted photons accompany the amplification, and a qualitative model including stimulated emission and ionisation dynamics of the NV− centre captures the dynamics in the experiment very well. These results highlight important considerations in the realisation of an NV− laser in diamond.

“…The peak emission cross-section is estimated to be σ em = (3.6 ± 0.1) × 10 −17 cm 2 at 710 nm for both samples. This value is ~8 times smaller than the one estimated in Vins et al [21]. However, the charge state of the NV centres was not discussed in [21] and the radiative lifetime assumed in the calculation of stimulated emission was not disclosed.…”

“…While there has been considerably less work on NV-for laser applications, a theoretical study predicted the potential for using laser action in NV-for magnetometry with fT/(Hz) 1/2 sensitivity [17,18], and recently an observation of stimulated emission in NV-in diamond was reported [19]. It has also been proposed that NV CC may possess promising properties for tunable solid-state lasers [20] in the visible spectral region: a luminescence bandwidth of ~120 nm and peak emission cross-section of 3.2x10 −16 cm 2 were reported when pumped at 532 nm [21].…”

In this paper, we analyse the prospects for using nitrogen-vacancy centre (NV) containing diamond as a laser gain material by measuring its key laser related parameters. Synthetic chemical vapour deposition grown diamond samples with an NV concentration of ~1 ppm have been selected because of their relatively high NV concentration and low background absorption in comparison to other samples available to us. For the samples measured, the luminescence lifetimes of the NV- and NV0 centres were measured to be 8±1 ns and 20±1 ns respectively. The respective peak stimulated emission cross-sections were (3.6±0.1)×10-17 cm2 and (1.7±0.1)×10-17 cm2. These measurements were combined with absorption measurements to calculate the gain spectra for NV- and NV0 for differing inversion levels. Such calculations indicate that gains approaching those required for laser operation may be possible with one of the samples tested and for the NV- centre

“…Through artful post treatment, such as thermal annealing and radiation treatment, some diamonds with dim luster can be changed to fancy color grade, and some nitrogen-related centers can be modified or even deliberately created. At the same time, some of the nitrogen-related optical centers have great potential in laser application, such as tunable high definition (HD) blue femtosecond lasers [11,12]. Or the spin tunneling of some nitrogen-related optical centers promisingly provide good quantum bits and logic gates for quantum computer [13].…”

the burgeoning multi-field applications of diamond concurrently bring up a foremost consideration associated with nitrogen. Ubiquitous nitrogen in both natural and artificial diamond in most cases as disruptive impurity is undesirable for diamond material properties, eg deterioration in electrical performance. however, the feat of this most common elementnitrogen, can change diamond growth evolution, endow diamond fancy colors and even give quantum technology a solid boost. this perspective reviews the understanding and progress of nitrogen in diamond including natural occurring gemstones and their synthetic counterparts formed by high temperature high pressure (hPht) and chemical vapor deposition (cVD) methods. the review paper covers a variety of topics ranging from the basis of physical state of nitrogen and its related defects as well as the resulting effects in diamond (including nitrogen termination on diamond surface), to precise control of nitrogen incorporation associated with selective post-treatments and finally to the practical utilization. among the multitudinous potential nitrogen related centers, the nitrogen-vacancy (NV) defects in diamond have attracted particular interest and are still ceaselessly drawing extensive attentions for quantum frontiers advance.
