Zusammenfassung:	Mode‐locking at repetition rate of 70 MHz with 115 fs spectral‐limited pulses was obtained in Yb3+:KY(WO4)2 laser with low loss saturable absorber. Special design and manufacture of saturable absorber incorporating InGaAs quantum wells separated by nanostructured barriers and a wide band total reflector resulted in the semiconductor saturable absorption mirror (SESAM) with short recovery time and low non‐saturable losses. This permitted to receive average output power of 1.57 W in mode‐locking regime close to 1.62 W power in continuous‐wave regime.
