The ER10000 is a high-performance, industrial-grade 1535 nm laser engineered for precision and durability in the most demanding environments. It delivers 10 mJ pulse energy with a 10 ns pulse width at a 5 Hz repetition rate, maintaining excellent ±5% energy stability. Featuring a high-quality TEM₀₀ beam with 4 mrad divergence and 0.8 mm diameter, it supports accurate long-range applications. Encased in a compact and rugged 110×40×24 mm aluminum housing (220 g), the ER10000 operates reliably across a wide temperature range (-40°C to +65°C), endures shocks up to 1500G, and offers a lifetime exceeding one million shots. Operating at 15V/80A, it is ideally suited for military target designation, LIDAR-based sensing, industrial laser processing, and advanced scientific research. This system combines robust construction with high pulse energy and thermal stability, making it an optimal solution for critical field and laboratory use.
