Description
We present an ultrafast SESAM modelocked thin-disk laser oscillator providing 550 W of average output power with 100-µJ, 852-fs-long pulses at a repetition rate of 5.5 MHz. This presents a record for average output power and pulse energy from a modelocked oscillator. Key developments are a new cavity design and high-power ion-implanted sapphire-bonded SESAMs. This oscillator can enable new frontiers in nonlinear optics. For example, using it to drive high-harmonic generation at megahertz repetition rates offers a route to enhanced sensitivity in attosecond pump-probe studies.
The laser is also well suited for industrial micromachining of metals, glasses and semiconductors.
