Abstract
In this letter, we demonstrated a LED-side-pumped hybrid Nd:YLF and Nd:glass laser achieving dual-wavelength operation at 1047 nm and 1053 nm without any optical tuning elements. In the quasi-continuous wave (QCW) regime, the laser achieved a maximum average power of 2.71 W at a 20 Hz repetition. Under active Q-switching, a peak output power of 2.087 kW was obtained with 184 ns pulse duration at 500 Hz repetition rate, while the beam quality factor (M2) measured 9.8. To the best of the authors’ knowledge, this is the first demonstration of a dual-wavelength laser using intracavity seeded light injection technology, providing a novel approach to extend laser emission into adjacent spectral regions and enabling stable terahertz radiation sources.
期刊介绍:
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
