Here, we expound upon a new theoretical design and experimental examinations for the attainment of a bicolor semiconductor disk laser. Numerical investigations are conducted in detail, disclosing that the dual-color gain with a separation spanning several tens of nanometers can be actualized via the accurate manipulation of the temperature-dependent quantum wells (QWs) gain-filtering and the disk microcavity-filtering. Employing this strategy, a 960/1000 nm gain chip is engineered. The experimental outcomes evinced that the emission wavelength can be adroitly shifted by governing the pump power or temperature. During the dual-wavelength operation, a near-diffraction-limited power of 3.8 W is procured, the beam quality factor M2 is in the vicinity of 1.1, and the brightness reaches approximately 310 MW/cm2sr. The quasi-continuous wave performances are also appraised under a duty cycle of approximately 10%. A pulse energy of 0.85 mJ and a peak brightness of around 0.75 GW/cm2sr is attained. Moreover, the dual-wavelength stability and synchronization are also corroborated. Overall, these investigative undertakings substantially augment the performance gamut of semiconductor lasers and can be construed as elongation and augmentation of the antecedent works in this discipline.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"12 5","pages":"2810–2818 2810–2818"},"PeriodicalIF":6.5,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144097839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

In enabling some of these applications, nonreciprocal thermal emitters will unavoidably need to serve as hot emitters. Leveraging magneto-optical effects, degenerate semiconductors have been demonstrated as a promising optical material platform for nonreciprocal thermal radiation. However, existing modeling and experimental efforts are limited to near room temperature (<373 K), and it remains unclear whether nonreciprocal properties can persist at high temperatures. In this work, we demonstrate strong nonreciprocal radiative properties at temperatures up to 600 K. We propose a theoretical model by considering the temperature dependence of the key parameters for the nonreciprocal behavior and experimentally investigate the temperature dependence of the nonreciprocal properties of sufficiently doped InAs, a degenerate semiconductor, using a customized angle-resolved high-temperature magnetic emissometry setup. Our theoretical model and experimental results show agreement, revealing that strong nonreciprocity can persist at temperatures over 800 K for high-temperature stable semiconductors, enabling a pathway for nonreciprocal radiative heat flow control at high temperatures.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"12 5","pages":"2767–2774 2767–2774"},"PeriodicalIF":6.5,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144097840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
