Outline of Final Research Achievements

To generate ultrashort pulses in 2 μm region, a laser oscillator is developed by using thulium-doped fibers made of fluoride glass known as ZBLAN, which has low absorption and low dispersion in the infrared region. By mode-locking the oscillator, pulses as short as 41 fs are obtained. These are the shortest pulses generated from laser oscillators operating around 2 μm region.
