Abstract

We report on an efficient continuous-wave (CW) and electro-optically (EO) Q-switched Tm:Lu₂O₃ ceramic laser resonantly-pumped at 1628 nm. In the CW operation, a maximum output power of 13.9 W at 2.07 μm was achieved with a corresponding slope efficiency of 65.1% and an optical efficiency of 48.8%. Under EO Q-switching regime, the Tm:Lu₂O₃ ceramic laser generated pulses with a maximum energy of 10.2 mJ and a minimum pulse width of 26 ns at a repetition rate of 1 kHz, yielding a peak power of 368.8 kW. Moreover, a beam quality factor (M²) of the Tm:Lu₂O₃ ceramic laser was measured to be approximately 1.3 at a maximum output level.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
