Erbium Glass Laser 1535nm Eye Safe Microchip DPSS Laser Module 40μJ

Erbium Glass Laser 1535nm Eye Safe Microchip DPSS Laser Module 40μJ

Model: ER40-01
The ER40 erbium glass laser operates at 1535 nm, providing Class 1 eye-safe performance. It delivers pulse energy of ≥40 μJ with a 4 ns pulse width at a 1 kHz repetition rate. With excellent pulse stability (10%), a 0.2 mm beam diameter, and a divergence angle of less than 15 mrad in TEM₀₀ mode, the ER40 ensures high-quality beam output. It is engineered to withstand harsh conditions, operating between -45°C and +65°C, and resisting impacts up to 1500 G and vibrations from 20–2000 Hz/20 G. Compact (17×8×7 mm) and lightweight (6 g), with a lifespan exceeding 5 million pulses, it operates at 2 V and 5 A. It is ideal for military rangefinder, LIDAR, laser communication, and eye-safe medical and industrial systems.

The ER40 1.54 μm DPSS Laser module is a compact and reliable eye-safe laser developed by ERDI TECH LTD, using Er:glass passive Q-switching technology. Built with a semiconductor packaging process, it offers excellent beam quality and stable single-pulse energy—perfect for high-performance applications.

This 1535nm erbium glass laser delivers consistent output across multiple frequency settings, with customizable options such as 70 μJ@500Hz, 40 μJ@1KHz, 20 μJ@2.5KHz, 10 μJ@5KHz, and 5 μJ@10KHz. Its versatility makes it ideal for laser ranging, LIDAR, laser irradiation, target identification, medical applications, and fiber optic communications.

With its small form factor and high stability, this 1.54 μm DPSS Laser is the perfect solution for precision-demanding tasks where size and safety are critical.
