Linewidths of lasers

The laser linewidth from stabilized low-power continuous-wave lasers can be very narrow and reach down to less than 1 kHz. Observed linewidths are larger than the fundamental laser linewidth due to technical noise (temporal fluctuations of the optical pump power or pump current, mechanical vibrations, … Se mer Laser linewidth is the spectral linewidth of a laser beam. Two of the most distinctive characteristics of laser emission are spatial coherence and spectral coherence. While spatial coherence is related … Se mer The laser linewidth in a typical single-transverse-mode He–Ne laser (at a wavelength of 632.8 nm), in the absence of intracavity line … Se mer • Laser • Fabry–Perot interferometer • Beam divergence • Multiple-prism dispersion theory • Multiple-prism grating laser oscillator Se mer History: First derivation of the laser linewidth The first human-made coherent light source was a Se mer One of the first methods used to measure the coherence of a laser was interferometry.
