1535nm Erbium Glass Laser 2mJ

The ERDI 2mJ 1535nm erbium-doped glass laser employs a proprietary Er:glass slab configuration (Er³⁺/Yb³⁺ co-doped phosphate glass) with stacked array pumping, delivering ​≥2mJ pulse energy​ while meeting ​Class 1 eye-safe certification​ (1535nm wavelength primarily absorbed by the cornea, eliminating retinal risk). It generates 12ns pulses at 5Hz repetition rate via passive Q-switching, ensuring energy stability (RMS≤3%) and superior beam quality (TEM00 mode, 5mrad full-angle divergence).
Featuring an ​ultra-compact package​ (60×25×13.5 mm³, 105g weight) and ​broad-temperature operation without TEC (-40°C to 65°C)​, it integrates a photodiode for real-time pulse monitoring. With 1500G shock resistance, it withstands harsh mobile platforms such as vehicle-mounted and UAV pod systems. Key applications include:

​Long-range sensing: High pulse energy + low atmospheric attenuation (0.1dB/km) enables ＞20km laser ranging and imaging;
​Tactical communications: 1535nm band compatibility with fiber optic windows reduces signal loss in field operations;
​Medical precision: High water absorption coefficient (~12cm⁻¹) optimizes corneal ablation and dental surgery;
​Military systems: Certified for extreme temperatures and vibration resistance, it integrates into firearm aiming systems and UAV payloads.
