Superresolution microscopy reaches 14 nm

The past decade has seen a growing interest in nitrogen vacancy colour centres (NV-centres) in diamond as prominent candidates for solid state quantum bits, single photon sources and even ultra-sensitive magnetic sensors.

These NV centres can be described by a three level energy scheme (Figure 1) made up of a spin 1 ground state 3A, a spin 1 excited state 3E and a meta stable singlet state 1A. The energy separation between the ground and excited states allows NV to be optically excited with 532 nm light and produces strong fluorescence from 637 nm to 800 nm.

    Torus SLM laser shows excellent spectral purity

    White papers | 3 Oct 2014

    The spectral purity of the torus 532 laser is shown to be 110 dB when measured with a Tandem Fabry-Perot interferometer, resulting in high resolution Brillouin scattering measurements in bulk materials.
