【Abstract】 A diode-pumped continuous-wave mode-locked femtosecond Yb∶KYW laser based on SESAM was successfully achieved.The properties of all-solid-state femtosecond lasers were systematically studied from the aspects of cavity design,dispersion calculation and compensation,modulation depth of SESAM and ultrafast pulse characteristic,respectively.SESAM with different modulation depth of 0.8%,2.4%,3.0% was applied in Yb∶KYW laser.The mode-locked laser with the pulse as short as 365 fs and the output power up to 253 mW was realized.更多还原
