The ER2000 represents the pinnacle of high-power laser diode technology, delivering ≥2 mJ pulse energy at 1535 nm (Class 1 eyesafe) with an ultra-stable ±5% pulse stability. Its 11 ns pulse width and fixed 5 Hz repetition rate ensure consistent performance for precision applications, while the TEM00 beam mode with 4 mrad divergence provides exceptional focus and beam quality. Engineered for extreme reliability, it operates in -45°C to +65°C, survives 1500G impacts, and features an industry-leading >50 million shot lifespan. The robust 60×34×26 mm housing (120g) makes it ideal for military-grade rangefinders, long-range LIDAR systems, scientific research, and industrial material processing. With 5V/65A operation, the ER2000 sets new standards for high-energy laser applications requiring durability, precision, and mission-critical performance in harsh environments.
