Q-switched thulium-doped fiber laser
TLDR

A tunable Q-switched thulium-doped single-mode silica fiber laser is presented for the first time. Its performance is analyzed as a function of pulse repetition rate and pumping power. The optimization of laser parameters resulted in 4 W/1 30 ns, 1 .92-jrm wavelength pulses generated at a 4-kHz repetition rate. From the measured values of small- signal attenuation and intrinsic saturation power, the thulium ion param- eters at the pump and signal wavelength are derived and used in the- oretical modeling of the laser. The moderate power required from the Ti:sapphire pump laser used in the experiment suggests that similar re- suIts can be obtained using a laser diode pump.read more
