Tunability and efficient CW laser operation in KLa(XO4)2:Nd

摘要

(KLM). KLW crystal was grown in air by top-seeded solution growth technique and KLM was grown by Czochralski technique. Details about crystal growth, structure, and optical spectroscopy will be summarized in presentation. In previous work [4], we study the 1 μm laser emission of the F3/2 à I11/2 transition and we observed some fluctuations in laser wavelengths but very smooth. However in this case we study in particular the potential effect of W or Mo ions in crystals with higher disorder than NaLa(WO4)2 respect to the laser tunability and output power in several laser configurations. In particular, we could summarize that KLW crystals offer a higher tunable range respect to KLM and KLM crystals present a higher output power than KLW crystals, in both cases laser threshold are very low around a few mW between 3 to 5 mW depending on the laser crystal.
