Fig. 1. Experimental setup of the diode-pumped Kerr-lens mode-locked femtosecond Yb:CYA laser. M1 and M2, concave mirrors with ROC of 75 mm; HR, high reflection mirror; OC, plane output mirror; P1 and P2, SF6 prisms. Lower pictures show the beam profiles for CW and KLM captured after the OC.
Fig. 2. Mode-locked pulse trains at (a) 20 ns/div and (b) 2 ms/div, respectively.
Fig. 3. (a) Intensity autocorrelation trace and (b) laser spectrum of the KLM pulses from the Yb:CYA laser. The blue dotted and the red solid curves in (a) are the experimental data and the sech 2
