{"version":"1.0","type":"link","title":"Complex beam parameter - Newikis","description":"In optics, the complex beam parameter is a complex number that specifies the properties of a Gaussian beam at a particular point z along the axis of the beam. It is usually denoted by q. It can be calculated from the beam's vacuum wavelength λ0, the radius of curvature R of the phase front, the…","provider_name":"Newikis","provider_url":"https://newikis.com","cache_age":86400}
