Table 2.1.2. CW mode-locked solid-state lasers using different mode-locking techniques. “Best” means in terms of pulse duration, highest average output
power, highest pulse repetition rate etc. – the result for which “best” applies is in bold letters. The lasers are assumed to be diode-pumped, if not stated
otherwise (except Ti:sapphire laser). ML: Mode-Locking. CCM: Coupled-Cavity Mode-locking. APM: Additive Pulse Mode-locking. RPM: Resonant Passive
Mode-locking. KLM: Kerr-Lens Mode-locking. SESAM: passive mode-locking using SEmiconductor Saturable Absorber Mirrors (SESAMs). Soliton-SESAM:
Soliton mode-locking with a SESAM. AOM: Acousto-Optic Modulator. EOM: Electro-Optic phase Modulator. λ0: center lasing wavelength. τp: measured
pulse duration. Pav,out: average output power. frep: pulse repetition rate.
