Dual-wavelength generation was achieved by utilizing the multimode interference (MMI) effect in a single-mode-six-mode-single-mode fiber structure, fabricated by splicing both ends of a six-mode fiber (6MF) to single-mode fibers (SMF). The output bandwidth of the TDFL and HDFL was 1954.65 nm to 1993.03 nm and 2068.63 nm to 2093.05 nm, respectively. A polarization controller (PC) was carefully adjusted to tune the output laser’s wavelength. Both setups demonstrated good stability, with SNR ranging from 48 to 55 dB for the TDFL and 41 to 50 dB for the HDFL. The power fluctuation was less than 1 dB. The maximum output power and slope efficiency of the TDFL were 24.3 mW and 5.90%, respectively, whereas those of the HDFL were 10.54 mW and 3.32%, respectively. A minimum linewidth of 0.07 nm was achieved across all wavelength configurations.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"62 2","pages":"1-7"},"PeriodicalIF":2.1,"publicationDate":"2026-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146175769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulations indicate that significant power levels are possible with polarizations ranging from planar to circular and at high harmonics of the XFEL resonance across this range of polarizations. These XFELs can be an important coherent source of hard x-rays through the gamma ray spectrum. For this purpose, we use the MINERVA simulation code.

The laser operates at a pulse repetition frequency (PRF) of 50 kHz with a gas-discharge tube (GDT) active volume of 0.115 L and achieves an output power of up to 6.5 W. The lasing pulse is shaped by a plane-parallel resonator, and the operating mode is maintained through independent thermal control of the CuBr and HBr reservoirs, as well as the active volume (GDT wall). Key laser characteristics, including single-pass emission and superradiance (amplified spontaneous emission ASE) components, are evaluated in the context of a brightness amplifier for laser monitor systems. Detailed experimental optimization of the discharge circuit and peaking capacitor value is presented. Comparative analysis with previously reported systems shows that the specific output power (56.5 W/L) exceeds that of earlier sealed-off GDT configurations employing tacitrons and semiconductor switches. The results demonstrate the potential of LTD-based power supplies for use in high-repetition-rate lasers and optical image amplifiers, particularly in high-speed imaging applications.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"62 1","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2026-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146082240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Supercontinuum generation based on OAM mode offers the potential to broaden the spectrum and enable new applications. While silica-based optical fibers have been successful in OAM supercontinuum generation, their strong absorption limits their use in the mid-infrared (>2500 nm) region. Fluoride glasses have been investigated as an alternative for supercontinuum generation, which could extend the corresponding spectrum to the mid-infrared wavelength range. In this work, we propose a ZBLAN (ZrF4-BaF2-LaF3-AlF3-NaF) ring-core fiber (RCF) for OAM modes supercontinuum generation. After adjusting the structural parameters, the OAM1,1 mode exhibits a flat dispersion distribution from 1500 nm to 5000 nm, with a <29> <tex-math>$cdot $ </tex-math></inline-formula> km) variation. By launching a 700-kW Gaussian pulse train centered at 2000 nm with 50-fs pulse duration into a 1.9-cm ZBLAN ring-core fiber, an over 2.5-octave supercontinuum spectrum based on the OAM1,1 mode can be generated with a spectral broadening from 863 nm to 4980 nm, with >0.99 coherence at −40 dB level. Furthermore, after using the same short-wavelength pulses with 1900 nm and 1550 nm incident wavelengths, the spectrum of OAM2,1 mode can be extended to a broadband supercontinuum from 780 nm to 3520 nm after 1.1 cm of transmission, whereas the maximum spectral broadening of the OAM3,1 mode (580 nm to 2620 nm) is reached after only 0.7 cm of transmission, with more than 2-octave and the coherence is >0.99 in all cases.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"62 2","pages":"1-10"},"PeriodicalIF":2.1,"publicationDate":"2026-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146175770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Operating at terahertz oscillation frequencies presents unique challenges based on the method of generation. Electronic oscillators can produce ample power but suffer from relatively high phase noise due to the nonlinear multiplication of microwave sources. Meanwhile, photomixing of optical sources provides superior spectral purity but low usable power, due to the limited bandwidth of the photomixer. We propose a hybrid solution involving injection locking of an electronic oscillator, a resonant tunneling diode, by a low phase noise photomixed source, a dual-wavelength Brillouin laser. In this study, we demonstrate a proof-of-concept injection-locking amplifier at 260 GHz, achieving up to 40 dB gain for nanowatt-level input signals. For the first time, we characterize the residual phase noise of an injection-locked waveguide RTD, showing quantitative consistency with theoretical predictions based on detailed analysis of its free-running noise. This architecture has the potential to scale to frequencies of 1 THz and beyond, which would provide a clear path to realize a terahertz oscillator with high power and low phase noise.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"62 1","pages":"1-7"},"PeriodicalIF":2.1,"publicationDate":"2026-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146082102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
