3 Terms and Definitions

GB/T 15313 and established the following terms and definitions apply to this document. For ease of use, repeat the following list GB/T 15313 certain terms and definitions. 3.1 Beam diameter beamdiameter du In the vertical plane the beam axis, containing the power (or energy) accounted for straight beam total power (or energy) a predetermined ratio (u%) of the smallest aperture path. When u = 86.5% when the subscript can be omitted. NOTE. To clarify, the beam diameter to identify the symbols and their use with the appropriate index, namely. du or dσ. [GB/T 15313-2008, the definition 2.1.49.1] 3.2 Waist diameter beamwaistdiameter d0, u Consists of a power position at the waist (or energy) is defined beam diameter du. NOTE. To clarify, the beam waist diameter symbol and logo to be used with a suitable index, namely. d0, u or dσ0. [GB/T 15313-2008, the definition 2.1.53.1] 3.3 Beam width beamwidths dx, u, dy, u Two are orthogonal to each other and perpendicular to the selected axis of the light beam on the x and y directions, consists of a power (or energy) of the total power (or energy) Predetermined ratio (u%) of minimum width. Note 1. The selected minimum direction is determined by the minimum beam width and the orthogonal direction. Note 2. For a circular Gaussian beam, dx, 95.4 = d86.5. Note 3. To clarify, the beam width to identify the symbols and their use with the appropriate index, namely. dx, u, dy, u or dσx, dσy.
