Route to All-Fiber Mamyshev Spatiotemporal Mode-Locked Laser With High Average Power/Pulse Energy
Spatiotemporal mode-locked (STML) fiber lasers exhibit potential for high-average-power output owing to larger mode field diameter in multimode fibers and great pump tolerance. However, the average power from the most of the reported STML lasers still remains in the order of several hundred milliwatts, or even lower, contrary to the virtues of multimode fibers. In this work, we construct an all-fiber Mamyshev STML laser and experimentally explore the influence of cavity losses on average power. By optimizing spatial mode filtering, regulating intra-cavity nonlinearity and compensating inter-modal group delay differences, spatiotemporal pulses with average power/pulse energy up to 2 W/135 nJ can be obtained with 2.2 ps temporal widths. Our study substantially expands the design possibilities for more powerful all-fiber STML lasers, rendering them much more amenable for practical implementation.
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.
