Free spectral range cavity
WebApr 4, 2024 · Absorption spectroscopy is a widely used analytical technique due to its label-free nature, however its application to small liquid samples is hampered by the associated short absorption pathlengths, which limit sensitivity. ... wavelength at ∼640 nm and measurements over a broad spectral range are difficult to achieve as they require the ... WebSufficiently high intracavity dispersion leads to the achievement of return-pass dispersive linewidths close to the free-spectral range of the cavity. Under these circumstances single-longitudinal-mode lasing is readily achieved as a result of multipass effects. Read more.
