A laser. The novel laser includes a gain medium, a pump source adapted to optically excite the gain medium in a first location, and a resonator adapted to extract energy from the gain medium in a second location distinct from the first location. In an illustrative embodiment, the gain medium is comprised of a plurality of solid-state gain particles suspended in a fluid. The gain medium is adapted to flow, and optical excitation of the gain medium occurs outside of the resonator. In a preferred embodiment, the flow velocity and the density of gain particles in the gain medium are adjusted for optimal absorption efficiency during optical excitation and then for optimal extraction efficiency in the resonator. In addition, the resonator may be shaped for optimal extraction efficiency, while pump modules that hold the gain medium during optical excitation are shaped for optimal absorption efficiency.

Modern broilers are selected for fast growth and a large proportion of breast tissue, contributing to a top-heavy phenotype, leg disorders, and inactivity as birds reach market weight. Therefore, the objective was to motivate broilers to move through environmental enrichment. Twelve hundred Ross 308 broilers were housed in pens of 30 for 6 wk; 600 birds were exposed to a novel laser enrichment device (LASER) and 600 were control. Each device projected 2 randomly moving red laser dots onto the floor 4 times / day for 4-min “laser periods”. Seven LASER and 7 control pens, with 5 focal birds / pen (n=70), were randomly selected to be video-recorded d0-8 and once weekly for the remainder of the trial. Videos were analyzed to measure broiler time-budget and behaviors such latency to feed and distance walked during laser periods. Focal birds were gait scored weekly on-farm. A test of the Human-Approach Paradigm was carried out on wk 1 and 6 on all pens. LASER birds were more active on d0, 1, 3, 4, 5, 7, and 8, moving 254% more on d7 (P≤0.05). Time spent active was increased in LASER treatment by 114% on wk 2; 157% on wk 3; 90% on wk 4; and 82% on wk 5. LASER birds spent more time at the feeder on d0, 1, 2, 5, 8, and on wk 1 and 5, with 84% more time at feeder than control on d5 (P≤0.05). LASER birds walked further during laser periods on d0-8, reaching 646.5 cm greater (d1), and on wk 2, 3, 4, and 5, with an increase of 367.5 cm on wk 2 (P≤0.05). Over wk 1-6, 60.54±7.4% of focal birds in the laser treatment were at the feeder during or within 5 mins following laser periods. The laser enrichment device was successful in stimulating broiler physical activity and feeding and did not negatively impact walking ability.Key words: broiler, environmental enrichment, well-being, lameness, behavior
