Actively Q-switched thulium-doped silica fiber laser at 0.82 μm
We demonstrate a Q-switched, cladding-pumped thulium-doped silica fiber laser operating at 0.82 μm, delivering energies up to 18 μJ in 530-ns pulses at a repetition rate of approximately 675 Hz. The system employs in-band pumping of an in-house-fabricated double-clad thulium-doped fiber (TDF). Q-switching was achieved by a mechanical optical chopper inside the laser cavity. To the best of our knowledge, this is the first reported demonstration of a Q-switched, cladding-pumped silica-based TDF laser at this wavelength, offering the potential for a power-scalable, compact, robust, and cost-effective source for high pulse energies in this wavelength range.
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.
