Abstract:
©2014 Optical Society of America We demonstrate passive mode-locking of a Tm,Ho-codoped crystalline laser operating on the Ho3+-ion transition 5I7→5I8 near 2 μm using a single-walled carbon nanotube saturable absorber. The Tm,Ho:KLu(WO4)2 laser emits nearly transform-limited pulses with duration of 2.8 ps at a repetition rate of 91 MHz. The output power amounts to 97 mW.
