1.7 μm diode-pumped Tm:GGAG and Tm, Ho:GGAG 2-2.1 μm laser
Original language description
The lasing of Tm or Tm,Ho-doped mixed gadolinium-gallium-aluminum-garnet (Tm:GGAG and Tm,Ho:GGAG) under 1.7 μm pumping was investigated for the first time. Three Tm:GGAG samples with Tm3+ concentrations 1.4 at.%, 2.5 at.% and 5.1 at.% (Tm/Gd) and one Tm, Ho:GGAG sample with concentration 0.4 at.% (Ho/Gd) and 4 at.% (Tm/Gd) in a form of face-polished plane-parallel plates were available. The original crystal boules were grown by Czochralski method in a slightly oxidative atmosphere. A fiber (core diameter 400 μm, NA= 0.22) coupled laser diode (Bright Lase Ultra - 100) was used to longitudinally pump each crystal placed in a water cooled (16 °C) heatsink. The laser diode was operated in a pulsed regime (up to 20 ms pulse duration, 10 Hz repetition rate, 1684 nm wavelength, output power amplitude up to 24 W) and CW regime (1690 nm wavelength, power up to 30 W).
