Abstract
Glasses doped with semiconductor quantum dots (QDs) are being extensively studied as promising materials for various photonics applications. In the near infrared region PbS(Se) QDs are very attractive to be used as saturable absorbers since their large bulk exciton Bohr radius and small energy gap at room temperature allow to vary the position of the first optical absorption resonance in a wide spectral range from 2.5 down to 1.0 μm only by varying QD’s size. We present Q-switch operation of Er:glass at 1.54 μm and Ho:YAG at 2.1 μm lasers using specially prepared PbS(Se)-doped phoshate glasses as saturable absorbers.
