a tunability of 35 nm between 1917-1951 nm, with a
maximum power of 3.84 W at 1934 nm wavelength.
The use of Etalon plates allowed us to reach a
narrow bandwidth of ~0.15 nm.
Comparing to previous work done with Tm:YAP
lasers, we report a first Watt level tunable narrow
bandwidth laser. Tm:YAP with the b-cut orientation,
which emits around the water absorption peak at
1940 nm, could be applicable for tissues ablation
with a controlled penetration depth, besides the other
applications of tunable source in the 2 μm region.
