ISO 13695:2004, Optics and photonics - Lasers and laser-related equipment - Test methods for the spectral characteristics of lasers

ISO 13695:2004 specifies methods by which the spectral characteristics such as wavelength, bandwidth, spectral distribution and wavelength stability of a laser beam can be measured. ISO 13695:2004 is applicable to both continuous wave (cw) and pulsed laser beams. The dependence of the spectral characteristics of a laser on its operating conditions may also be important.
