摘要

Progress in the development of efficient and reliable diode-pumped femtosecond laser systems based on both Kerr-lens and saturable-absorber mode locking is reported. Efficient Kerr-lens mode locking in diode pumped ytterbium-doped lasers, namely Yb:KY(WO_4)_2 (Yb:KYW) and Yb:YVO_4, is demonstrated with average output powers in excess of 1W, pulse durations around 100fs and electrical-to-optical efficiencies that exceed 15%. Novel semiconductor saturable absorbers based on InAs/InGaAs quantum dots are described and their applicability for efficient femtosecond pulse generation from near-infrared solid-state lasers is discussed. Efficient passive mode locking in the spectral regions around 1.3μm and 1.55μm in Cr:forsterite and the more recently developed Er, Yb:YAl_3(BO_4)_3 crystalline lasers has been demonstrated using low-loss InGaNAs saturable absorbers. A few examples of applications for this category of robust and efficient femtosecond lasers have been included. Specifically, the characteristics of a femtosecond visible light source producing pulses as short as 200fs at 520nm are outlined.
