ERDI MINI-ER100 Microchip Laser Module: Leading the Way in 1535nm Erbium Laser Technology

Introduction

The MINI-ER100 Microchip Laser Module, developed by our company, represents a significant advancement in 1535 nm solid-state laser technology. Utilizing state-of-the-art Er:Glass and Co:Spinel composite crystals, this compact yet powerful module delivers exceptional performance, making it ideal for a broad spectrum of applications—from laser ranging to fiber-optic communications. With pulse energy of ≥100 μJ, Class 1 eye-safe certification, and a rugged design, the MINI-ER100 sets a new benchmark in erbium laser solutions.

Principle and Core Technology

The MINI-ER100 operates on Erbium-doped glass (Er:Glass) technology, known for its high efficiency and long-term stability at the 1535 nm wavelength—a spectral region considered eye-safe and optimal for outdoor and defense applications. The incorporation of Co:Spinel crystals significantly enhances thermal conductivity and output stability, enabling high pulse repeatability (≤10% pulse-to-pulse variation) and a narrow pulse width of just 3.5ns.

The module's microchip architecture employs advanced bonding and packaging techniques to achieve a highly compact form factor (14.5×6.3×4.37 mm³; 2.5 g) without compromising on performance. Operating in the fundamental TEM₀₀ mode, the laser delivers excellent beam quality with a raw beam diameter of 0.3 mm and a divergence angle of 10 mrad—key characteristics for precision targeting and alignment applications.
