We demonstrated a high-power continuous-wave (CW) dual-wavelength Ho-doped fiber laser (HDFL) at 2049 nm and 2153 nm with a simple coupled-cavity configuration. A ~100 W laser diode-pumped fiber laser at 1150 nm served as the pump source. The maximum output power reached ~22.3 W and the slope efficiency was 23%. By altering the incident pump power, the power ratio of two signal wavelengths could be tuned in a large range due to gain competition. As far as we know, this is the first CW dual-wavelength HDFL with the power exceeding ten-watt-level, and the first dual-wavelength HDFL with the central wavelengths exceeding 2.0 μm and 2.15 μm respectively.

Purpose Of Review: This review focuses on recent advancements in laser technologies used in urology, particularly in enucleation, vaporization, lithotripsy, and focal laser ablation (FLA). The growing use of the thulium fiber laser (TFL) and the development of pulsed thulium lasers (p-Tm:YAG) highlight the relevance of this review, as these innovations aim to improve precision and outcomes in urological procedures.
Recent Findings: Recent studies have shown the advantages of TFL in achieving precise tissue ablation, reduced retropulsion offered by the Moses technology in holmium lasers, and the potential of pulsed thulium lasers for more precise control of the effects on tissues.

Clinical benefits of immunotherapy in colorectal cancer (CRC) are limited due to the low immunogenicity and immunosuppressive tumor microenvironment. Fusobacterium nucleatum (Fn) is discovered to colonize CRC tumors and dampen immunotherapy by fostering an immunosuppressive TME. Herein, a controllable "Shielding-deshielding" N-acetylgalactosamine (GalNAc)-derived photothermal nanotherapeutic is developed to mediate cascade targeting toward tumor and intratumoral Fn for enhanced photothermal-immunotherapy.

Photothermal treatment has attracted immense interest as a promising approach for biomedical applications such as cancer ablation, yet its effectiveness is often limited by insufficient laser penetration and challenges in achieving efficient targeting of photothermal agents. Here we developed a transvascular interventional photothermal therapy (Ti-PTT), which employed a small-sized microcatheter (outer diameter: 0.60 mm, 1.

The large-scale mining and utilization of rare earth elements have significantly increased their concentration in the environment, especially in regions surrounding mining areas. These environmentally-enriched rare earth elements accumulate in agricultural products and organisms through soil and water, potentially impacting in human health through the food chain. Erbium (Er), a rare earth element of the lanthanide series (Group IIIB), plays a crucial role in various modern technological applications.

Aim: To investigate the effectiveness of unconventional post space disinfection techniques, specifically Er:YAG laser, Temoporfin, and Carbon Nanoparticles (CNPs), in improving Martens hardness (MH), eliminating the smear layer (SL), and enhancing the push-out bond strength (PBS) of glass fiber posts in canal dentin.
Methods: An in vitro study was conducted utilizing 80 single-rooted extracted human teeth, which were decoronated and subjected to standardized root canal preparation. The teeth were equally distributed into four experimental groups: Group 1 (NaOCl + EDTA), Group 2 (Er: YAG laser + EDTA), Group 3 (Temoporfin + EDTA), and Group 4 (CNPs + EDTA).
