While traditional lasers operate on the principle of light amplification (photons), sound lasers work similarly but with sound waves (phonons) instead. Phonons are the quantized units of vibrational energy that move through matter, and sound lasers use these vibrations to create a coherent, focused beam of sound. This process mimics …

In the ever-evolving landscape of naval and special operations, small Unmanned Underwater Vehicles (UUVs) are emerging as transformative tools for missions ranging from intelligence gathering to mine countermeasures. Defined as vehicles under 45 inches in length and weighing less than 200 pounds, these compact systems are designed to balance endurance, …
