Optical properties and laser action of H3 center in synthetic diamond

Abstract

Color centers in diamond have a potential for opto-electronic applications. Laser action of H3 centers in natural diamond has been already reported. Our interest is focused on the possibility of laser action using synthetic diamond. A first attempt was made to produce H3 centers with high density in synthetic diamond. Optical properties of the H3 centers were investigated. Sample-dependent luminescence decay time and long lived transient absorption were observed. Laser action using the H3 centers in synthetic diamond occurred though the efficiency was as low as 0.1%.

Visible color-center laser in diamond

Stephen Colby Rand, L. G. DeShazer

Laser action at 530 nm using H3 centers in diamond was observed with an efficiency of 13.5% at room temperature. Optical double-resonance experiments on N3 centers provided direct evidence for a (2)A metastable level. Its presence results in rapid decay of the excited (2)E state and low quantum efficiency as well as significant excited-state absorption in the N3 luminescence region.

One-Photon Femtosecond Laser Excitation of Photoluminescence from H3 and H4 Centers in Natural Diamond: A Method to Determine Their Concentration

Sergey Ivanovich Kudryashov, П. А. Данилов, Victor G. Vins +6 more

The photoluminescence spectra of the dominant H3 and H4 centers in a natural diamond sample, which is preliminarily characterized by optical and infrared spectrophotometry, are excited by femtosecond laser pulses with a wavelength of 470 nm and varying intensity. Saturation of the photoluminescence intensity of the H3 and H4 centers normalized by the intensity of laser radiation is observed and attributed to the saturation of the resonance transition responsible for the excitation. This makes it possible for the first time to estimate the absorption cross sections of H3 and H4 centers, which can be compared with values known from the literature and those determined from photoluminescence kinetics. The total concentration of H3 and H4 centers can then be found. Taking into account the known absorption coefficient of the sample at a wavelength of 470 nm and the previously established ratio of the contributions from H3 and H4 centers, their concentrations have been estimated separately for the first time.

Properties of color centers in diamond studied by methods of femtosecond laser spectroscopy

Neli Streshkova

In this work, we focus on the interaction of SiV color centers in diamond with femtose- cond light pulses. In the theoretical part, a script is developed to simulate the experimen- tal varying stripe length method and the effects of saturated optical gain are investigated. In the experimental part, photoluminescence and transient differential absorption under non-resonant excitation are studied. The result of the luminescence measurements are estimates of the effective cross-sections of single-photon absorption for the wavelengths 620 nm, 515 nm and 340 nm, as well as the effective cross-section of three-photon absorp- tion for 2000 nm. The result of the differential absorption measurements is the relaxation constant of the excited level of the SiV center and the upper estimate of the time duration of the initial dynamics. 1

Luminescent Diamond: A Platform for Next Generation Nanoscale Optically Driven Quantum Sensors

Nicholas A. Nunn, Alexander I. Shames, Marco D. Torelli +2 more

Luminescent diamond of technological importance primarily originates from synthetic material as opposed to natural diamond. Detonation synthesis is an ideal method for bottom-up synthesis of nanoscale particulate diamond at large scale; it is unfortunately not currently suitable for the production of luminescent diamond hosting optical centers. Electron beam irradiation is a widely used approach for introducing vacancies in diamond particles. Optical centers in diamond are exceptional candidates for next generation solid-state quantum sensors. Techniques to produce synthetic diamond can be grouped into two broad categories: static synthesis and dynamic synthesis. High pressure high temperature synthesis attempts to mimic the growth conditions of natural diamonds formed deep within the Earth’s mantle. Chemical vapor deposition diamond is produced via plasma assisted growth on a heated substrate at either atmospheric or, reduced pressure using a gas phase carbon precursor in hydrogen. Quantum sensing enabled by optical centers in diamond primarily relies on magnetic interactions associated with the optical center and their surrounding environments.

Generation of laser radiation by color centers in diamond crystals (review)

V. P. Mironov, E. A. Protasova, E. I. Lipatov +1 more

This review analyzes theoretical calculations and laboratory experiments showing the prospects of using of diamond with color centers as active laser medium. Despite the mentioned prospects, practical implementation of lasers based on color centers in diamond is limited to laboratory demonstrations. No commercially significant products of laser technology based on diamond with color centers have been created yet. Obviously, the available scientific information is still insufficient, and additional research is required. The review analyzes the factors that require further study: concentration quenching of luminescence, thermal quenching of luminescence, luminescence quenching by nitrogen and other impurity defects, as well as the influence of multiphoton and multi-stage absorption processes. For color centers in diamond, such processes have yet to be investigated in more detail.
