We demonstrate for the first time silicate bonding of a SESAM to a sapphire superstrate to control the sign and magnitude of the SESAMs thermal lensing. We demonstrate modelocking in a 233-W average-power thin-disk laser.

We present a 350-W 940-fs thin-disk oscillator. We achieve this new record-high average power ultrafast oscillator through vacuum operation, multiple passes on the disk, and large pump spot. Systematic power-scaling through multi-pass cavities is dis
