For the use of an IR beam expander and IR lenses to enlarge, collimate, and focus the beam from a Thulium fiber laser into small, flexible, 50-micrometer-core, optical fibers, for fragmenting kidney stones.

Kidney stone disease affects approximately 10% of the U.S. population, and its prevalence is increasing due in part to epidemics of obesity, diabetes, and climate change. The solid-state Holmium:YAG laser has been used in the clinic for lithotripsy for the past 30 years. However, the Thulium fiber laser offers several advantages, including faster stone ablation rates, less stone retropulsion, less fiber burn-back, and an improved spatial beam profile for coupling into smaller and more flexible optical fibers (50 micrometer core fibers) compared to the Holmium laser (200 micrometer core fibers). Smaller and more flexible fibers consume less space in the working channel of the flexible endoscope used to deliver the laser fiber inside the urinary tract. The air-cooled Thulium fiber laser is also more compact, quieter, and less expensive than the water-cooled Holmium laser.

For a system to measure the heating value of vegetation employing the absorption of cellulose and thermal difference.

The heating value of vegetation species is valuable information to estimate the hazard of beginning and spreading forest fires. A traditional measure method is utilized to evaluate this parameter and consists in collecting, drying, and grinding a group of leaves. Afterward, a calorimetric bomb generates an adiabatic process to measure the heating value. This method takes around 12 hours to complete. This system proposes a new approach to measure the heating value of vegetation by optics methods. The procedure uses the specific optical absorption of cellulose, hemicellulose, and lignin to generate a thermal difference on the surface of a single leaf. The measurement only requires the optical power absorption to determine the increase of the temperature and estimate the heating value of the sample, decreasing the time-per-measurement to a few minutes.

For the development of a portable, low-cost, real-time analysis platform for street drugs, coupled with integrated harm-reduction messaging. The goal is for this platform to be deployed in communities without the need for an experienced technician to interpret the data.

Drug checking technologies enable people who use drugs (PWUD) to obtain complete information on the composition of substances and, ideally, the potency of the active components of drug mixtures. This knowledge empowers PWUD to make informed decisions that are potentially lifesaving in the context of an unregulated illicit drug supply. Barriers to accessing such a service include lack of available testing technologies outside urban areas, and stigma associated with drug use that prevents wide-spread testing. The goal is to create a low-cost, AI-driven platform that can be utilized at harm-reduction centers without the need for a trained technician. The device will also provide data to inform local communities of what is circulating in their regions.
