The high output of green laser pointer can meet the requirement of the large quantity order
However, there m beam along the radial section line round the number, n Table 117 shows the number of nodal lines of the beam along the direction of the angle made its transverse mode graphics can be found in Figure 3-3 (e, f, g). This directly gives the Laguerre-Gaussian beam spot the radius ωmn (z) …
