In the free-running laser operation, co-lasing could be observed at the wavelengths of 2096 nm and 2325 nm. The laser operation and power performance of the 3F4→3H6 and 3H4→3H5 transitions were investigated separately with a birefringent tuning plate. By using a double-end-pumped x-cavity, 134 mW of CW output power was obtained at the wavelength of 2309 nm with 4 W of pump power and with 7% slope efficiency. By using two sets of cavity optics, we further achieved the broadest, continuous tuning range, obtained to date for a Tm3+ laser, extending from 1845 nm to 2328 nm. We also investigated a 2-µm laser operation, where with a 1.3% output coupler, a maximum CW output power of 917 mW was obtained at 2094 nm with 3.93 W of pump power. By using the laser threshold and power efficiency data measured during the 2.3-μm operation, the emission cross section of the Tm3+:Lu2O3 ceramic gain medium was determined to be 3.24 × 10-21 cm2 at the wavelength of 2309 nm.","PeriodicalId":19540,"journal":{"name":"Optics letters","volume":"50 4","pages":"1220-1223"},"PeriodicalIF":3.1,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143416693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional approaches often rely on separate devices for communication and sensing, which can compromise spectral efficiency and increase system complexity. This work presents an innovative method for integrating communication and sensing within a conventional optical supervisory channel. Four QPSK data streams with different duty ratios enable robust communication and precise sensing with a 125-MBaud transmitter. The forward transmission of communication signals is demonstrated with impeccable accuracy, delivering bit-error-free performance over two fiber links. Concurrently, sensing data is extracted through polarization-diversity reception of the backscattering signal. The distributed acoustic sensing sensitivity achieves 0.50 nε/Hz in 10.2 km and 0.65 nε/Hz in 40.0 km at a spatial resolution of 10 m by employing a matched filter. This approach effectively adopts the defined forwarded transmitted control signals or channel information signals, such as channel power, optical signal-to-noise ratio, and Q-factor, simultaneously achieving sensing applications without any dedicated channel or resource.","PeriodicalId":19540,"journal":{"name":"Optics letters","volume":"50 4","pages":"1409-1412"},"PeriodicalIF":3.1,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143416848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The FTFs based on TeO2-BaF2- Y2O3 glasses were fabricated by using a rod-in-tube method. The doping concentration of Tm3+ ions in the core was about 4000 ppm and that of Tb3+ ions in the fiber cladding was about 10,000 ppm. By introducing the Tb3+ ions into the cladding, the emission in the long-wavelength region (>1750 nm) originating from the transition 3F4→3H6 of Tm3+ ions was suppressed efficiently by broadband absorption (1700-2100 nm) originating from the transitions 7F6→7F0,1,2 of the Tb3+ ions in the cladding. As a result, a positive net gain ranging from 1600 to over 1680 nm was achieved in a 1.5 m long Tm3+-doped FTF as the launched power of the 1212 nm laser was about 3 W. The gain value at 1675 nm was about 19.7 dB for an input signal power of ∼0 dBm (or 1 mW). The gain was gradually reduced for shorter wavelengths, but it was still above 10 dB at ∼1644 nm. Our results show that Tm3+-doped FTFs with a Tb3+-doped cladding are promising gain media for constructing fiber amplifiers and lasers in the wavelength region of 1600-1700 nm.","PeriodicalId":19540,"journal":{"name":"Optics letters","volume":"50 4","pages":"1413-1416"},"PeriodicalIF":3.1,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143416889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
