Mode-locking of the disordered cubic sesquioxide crystal Yb:LuScO3 using a single-walled carbon nanotube saturable absorber (SWCNT-SA) is demonstrated under diode pumping and compared with passive mode-locking by a commercial semiconductor saturable absorber mirror (SESAM). Around 1 µm, passive mode-locking using SWCNT-SAs was demonstrated for Yb-doped double tungstate lasers (Yb:KLuW, Yb:KYW) [1]. Using a SWCNT-SA directly deposited on a dielectric mirror for passive mode-locking of an Yb:LuScO3 laser, nearly transform-limited pulses with a duration of 306 fs were achieved. The comparison with SESAM mode-locking indicates the directions for future optimization of the SWCNT-SA parameters. The shortest pulse duration of 125 fs for Yb-doped SESAM mode-locked sesquioxide lasers confirms our approach of introducing mixed sesquioxide hosts to profit from their increased gain bandwidth compared to the sesquioxide crystals without compositional disorder.
