TaO/SiO high reflection (HR) interference coatings for λ∼1 μm offer superior performance at high irradiance conditions. However, these coatings are not good candidates for high peak power conditions in comparison to HfO/SiO multilayer stacks. Here we show that the modification of the top layers design of a quarter wave TaO/SiO high reflector leads to 4-5 fold increase in the laser damage fluence compared to a quarter wave (TaO/SiO) when tested at λ=1.03 μm using pulse durations of 0.19 and 4 ns and peak power densities of 43.5 and 216 GW/cm. One of the designs achieved a laser damage threshold fluence of 174 J/cm at 4 ns, which is 10% higher than that of a HfO/SiO quarter wave design.
Endometriosis and adenomyosis are debilitating gynecological conditions that severely affect the quality of life of women. Traditional diagnostic and treatment methods, including laparoscopic surgery and hormonal therapy, face significant limitations such as incomplete lesion detection, high recurrence rates, and adverse side effects. Emerging bioengineering technologies offer promising solutions for precise diagnosis and therapy of these diseases.

Triclocarban (TCC) is a common antimicrobial agent that has been widely used in medical care. Given the close association between TCC treatment and metabolic disorders, we assessed whether long-term treatment to TCC at a human-relevant concentration could induce nephrotoxicity by disrupting the metabolic levels in a mouse model. Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) was applied to investigate the alterations in the spatial distributions and abundances of TCC, endogenous and exogenous metabolites in the kidney after TCC treatment.
Fluorescence-guided surgeries, including tumor resection and tissue soldering, are advancing the frontiers of surgical precision by offering enhanced control that minimizes tissue damage, improving recovery and outcomes. However, integrating fluorescence visualization with real-time temperature monitoring remains a challenge, limiting broader clinical use. We address this issue with an augmented reality (AR) visor that combines nanomaterial excitation, fluorescence detection, and temperature monitoring.
The primary objective of urolithiasis therapy is complete stone removal and highest stone-clearance rates possible to minimize recurrence. A novel approach that employs a magnetic suspension and a magnetic probe for the passive collection and removal of small residual fragments was developed. This study assessed the feasibility of this system in porcine models.

Infrared nonlinear optical (NLO) crystal materials exert a crucial role in laser technology, which is extensively utilized in the fields of medical laser, long-distance laser communication, infrared laser guidance, etc. Currently, the commercially available infrared NLO crystals are diamond-like structural crystals AgGaQ (Q = S, Se) and ZnGeP. However, their applications are significantly limited owing to their inherent drawbacks, such as low laser damage thresholds and narrow band gaps.
