Abstract

Transmission-type single-walled carbon nanotube saturable absorbers were successfully fabricated and used in a CW passively mode-locked $\mathrm{Yb}\text{:}{\mathrm{Y}}_2{\mathrm{SiO}}_5$ laser for the first time to our knowledge. We obtained pulses as short as $1.1\mathrm{ps}$ around a center wavelength of $1058\mathrm{nm}$. The average output power of $1.1\mathrm{W}$ was achieved at the repetition of $96.7\mathrm{MHz}$; the corresponding peak power and energy of a single pulse was $10.3\mathrm{kW}$ and $11.4\mathrm{nJ}$, respectively.
