Over 300 mW Single-Frequency Distributed Bragg Reflector Fiber Laser at 2.04 μm Based on Tm:YAG/Ho:YAG Co-Derived Silica Fiber
Several Tm:YAG/Ho:YAG co-derived silica fibers (THCDSFs) were fabricated using the molten core (MC) method. A maximum gain coefficient of 5.16 dB/cm at 2040 nm was obtained for the THCDSF prepared through the utilization of a spliced piece of semi-cylindrical 15.0 at% Tm:YAG and 2.5 at% Ho:YAG crystals as the core precursor material. Employing a 2.0-cm-long THCDSF and in-band pumping with a 1610 nm fiber laser, a stable single-frequency distributed Bragg reflector (DBR) laser operating at 2040 nm was demonstrated. The fiber laser has a maximum output power of 306 mW and a slope efficiency of 19.3% for the absorbed pump power. To the best of our knowledge, this represents the maximum recorded output power of a single-frequency dBR short-cavity laser oscillator above 2 μm to be reported.
期刊介绍：
The Journal of Lightwave Technology is comprised of original contributions, both regular papers and letters, covering work in all aspects of optical guided-wave science, technology, and engineering. Manuscripts are solicited which report original theoretical and/or experimental results which advance the technological base of guided-wave technology. Tutorial and review papers are by invitation only. Topics of interest include the following: fiber and cable technologies, active and passive guided-wave componentry (light sources, detectors, repeaters, switches, fiber sensors, etc.); integrated optics and optoelectronics; and systems, subsystems, new applications and unique field trials. System oriented manuscripts should be concerned with systems which perform a function not previously available, out-perform previously established systems, or represent enhancements in the state of the art in general.
