Abstract :
Tm3+ is a very interesting ion for both realization of infrared lasers. We have measured the excited state absorption and gain for Tm3+:BaYF crystals with the concentration of 5, 8, 12 and 18%, Tm3+:YLF with the concentration of 6% and Tm3+:KYF with the concentration of 15%. The investigations are based on pump and probe measurements using the double modulation technique with two lock-in amplifiers.
