G. Spuhler et al., Passively modelocked diode-pumped erbium-ytterbium glass laser using a semiconductor saturable absorber mirror, ELECTR LETT, 35(7), 1999, pp. 567-569
A diode-pumped bulk Er3+:Yb2+:glass laser has been passively CW modelocked
for thr first time. Reliable, self-starting passive modelocking using semic
onductor saturable absorber mirrors (SESAMs) is demonstrated, with pulses a
s short as 2.5 ps bring obtained with an average output power of 68mW at th
e telecommunications wavelength of similar to 1.5 mu m.
