Brillouin lasers providing extremely narrow-linewidth are emerging as a powerful tool for microwave photonics, coherent communications, quantum processors, and spectroscopy. So far, laser performance and applications have been investigated for a hand

We report an investigation into secondary mode suppression in single longitudinal mode (SLM) 1240 nm diamond Raman lasers. For a three-mirror V-shape standing-wave cavity incorporating an intra-cavity LBO crystal to suppress secondary modes, we achie

Here we introduce a fiber amplifier and a diamond Raman laser that output high powers (6.5 W, 1.3 W) at valuable wavelengths (1060 nm, 1250 nm) for two-photon excitation of red-shifted fluorophores. These custom excitation sources are both simple to

Here we introduce a fiber amplifier and a diamond Raman laser that output high powers (6.5 W, 1.3 W) at valuable wavelengths (1060 nm, 1250 nm) for multiphoton excitation of red-shifted fluorophores. These custom excitation sources are both simple to

Introduction: The incidence of acetabular fractures in older patients is increasing. The management of these patients is evolving due to the recognition of risks associated with prolonged immobility with conservative treatment. Materials and methods:

We demonstrate a frequency-tunable THz polariton source based on stimulated polariton scattering (SPS) in MgO:LiNbO3. The system produces THz emission using an intracavity shallow-bounce configuration. Continuously tunable THz emission across the fre

We demonstrate a new, to the best of our knlowledge, cavity design for terahertz (THz) lasers based on stimulated polariton scattering (SPS). The design simplifies the angle tuning of these lasers, which require non-collinear cavity fields at fundame

In recent years diamond Raman lasers have become of interest for high power, single longitudinal mode (SLM) lasing. These systems benefit from the wavelength agility provided by the Raman mechanism, the lack of spatial hole burning in Raman gain medi

We propose a high-sensitivity magnetometry scheme based on a diamond Raman laser with visible pump absorption by an ensemble of coherently microwave driven negatively charged nitrogen-vacancy centres (NV−) in the same diamond crystal. The NV− cen
