Illustration of the KLM Yb:YAG thin disk laser and SHG process. TDM: thin disk module (D+G, TDM 1.0); M1 and M2: concave mirrors with the ROC of 150 mm; FS: fused silica plate positioned at the Brewster angle in the focus of M1 and M2; OC: output coupler with 8% transmission; HD1 and HD2: flat high-dispersive mirrors with GDD of −3000 fs2 per bounce; HR: high reflective mirror; H: hard aperture; HWP: half wave plate; TFP: thin film polarizer; L1 and L2: 50 mm focal lenses; DM: dichroic mirror.
