Tm doped fiber laser,ultrafast pulse

Tm-doped fibers (TDF) with a wide gain bandwidth in the 2 µm range are suitable for high-power ultrashort pulse lasers. Recently, high-power, short-pulse Tm-doped fiber lasers have been reported. This development holds promise for applications in the mid-infrared region, such as molecular spectroscopy and laser processing. We are working on developing high-power femtosecond laser sources based on Tm-doped fiber lasers. In this presentation, we report on the amplification of pulses, achieving an output of 35 W with a pump power of 140 W.
