1535nm Eye-safe Diode Pumped Solid State Laser | DPSS Laser 1mJ

Model: ER1000-01
The ER1000 is a high-performance, Class 1 eye-safe laser diode operating at 1535 nm, delivering ≥1 mJ pulse energy with an 8 ns pulse width and 1–5 Hz repetition rate. Featuring exceptional energy stability (3% RMS) and a high-quality TEM₀₀ beam with low divergence (7 mrad), it ensures precision and reliability in critical applications. Built for extreme environments, it operates in -40 °C to +65 °C and withstands 1500 G impacts and 20 G vibrations. Its compact size (40×9×7.7 mm) and lightweight (20 g) make it ideal for long-range LIDAR, military targeting, industrial laser ranging, and scientific research. With a rugged design and >5 million pulse lifespan, the ER1000 is perfect for aerospace, defense, and environmental monitoring systems requiring high power and durability in challenging conditions.

This high-performance 1535nm DPSS laser is eye-safe and delivers strong pulse energy of ≥1mJ, making it ideal for demanding applications like long-distance laser ranging and electronic communication systems.

Built using robust DPSS Laser (Diode-Pumped Solid-State) technology, this laser operates efficiently at low pulse repetition rates (typically under 10 Hz). This DPSS Laser is the core engine behind advanced rangefinders achieving exceptional distances – up to 20 kilometers.

Renowned for its high stability, this reliable laser source is perfect for critical applications including firearm aiming systems and UAV (drone) pods.
