Thulium doped sesquoxide transparent ceramics for high energy class laser in nano second regime at cryogenic temperature

The goal of the proposed project is to develop thulium doped sesquoxide transparent ceramic high-energy class laser in nano second regime at cryogenic tempearture. To reach this goal, high quality Tm:Y2O3 transparent ceramic of different doping will be fabricatied. The fabricated transparent ceramic will be characterized in terms of absorption and photoluminescenceat cryogenic temperature (10 K – 300 K). Finally, the fabricated transparent ceramic will be tested in laser resonators to study the impact on laser performance in continous-wave regime and pulsed regime (active and passive Q-switching) at cryogenic temperatures.
