Femtosecond Upconversion Pumped 2.3-μm Thulium Laser
Thulium lasers operating on the <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup>H<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</inf>→<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup>H<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</inf> transition represent a viable solution for generating broadband emission in the short-wave infrared, at 2.2-2.5 μm, with a potential of supporting femtosecond pulse generation in the mode- locked regime. Upconversion pumping relying on the photon avalanche mechanism is a key technology enabling power scaling of such sources [1], [2]. We report on emission-cross-section limited soliton pulses from a passively mode-locked Tm laser at <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$2.3 \mu \mathrm{m}$</tex> employing a GaSb-based semiconductor saturable absorber mirror (SESAM).
