Fig. 6From: Intracavity spherical aberration for selective generation of single-transverse-mode Laguerre-Gaussian output with order up to 95Typical beam patterns obtained with different δ, when using lenses of focal length f1 = 150 mm and f2 = 51.8 mm. The lowest and highest order of eigenmodes obtained are LG0,±32 (δ = 4.5 mm) and LG0,±95 (δ = 5.6 mm) under the pump power of 1.20 WBack to article page
