Abstract

Progress in the development of efficient and reliable diode-pumped ytterbium femtosecond laser systems based on Kerr-lens mode locking effect is reported. Average output power of up to 1 W is demonstrated in a Kerr-lens mode locked Yb:YVO₄ laser with pulse durations as short as 80 fs at a pulse repetition frequency of 79 MHz. Measurements of the nonlinear refractive indexes of the Yb³⁺:YVO₄ crystal, n₂, were performed and were determined to be 39×10^-16cm²/W and 49×10^-16cm²/W for E||c and E⊥c polarizations, respectively. These results were found to be in a good agreement with those calculated using both the Kramers-Krönig relation and Boling, Glass and Owyoung formula. Keywords: Mode-locked lasers, diode-pumped lasers 1.
