Imagine a laser system that unifies rangefinding and target designation into a single, streamlined optical path. No more bulky dual setups, no alignment headaches—just plug-and-play precision. This isn’t sci-fi; it’s co-aperture technology, and it’s transforming military and aerospace applications. Today, we’ll dive into why 1064nm semiconductor-pumped solid-state lasers are at the heart of this revolution.
Why 1064nm? The Science Simplified
The 1064nm wavelength sits in the near-infrared spectrum, offering two critical advantages:
1️⃣ Eye Safety: Absorbed minimally by the cornea, reducing collateral risks.
2️⃣ Atmospheric Penetration: Performs reliably through haze, smoke, or light fog.
Paired with co-aperture design, these lasers merge rangefinding and illumination beams into one emission path. The result? Smaller footprints, faster deployment, and rock-solid reliability.
Key Advantages of Co-Aperture Systems
✅ Size & Weight Reduction
Traditional dual-system setups are being phased out by units like G Series (≤1.95kg). This is critical for airborne and portable applications.
✅ Plug-and-Play Simplicity
Forget warm-up times. Modern systems like the G Series activate instantly, while HDL models ready in ≤1 minute.
✅ Precision Engineering
Beam divergence as low as 0.12 mrad (SFC80G) ensures energy stays focused on distant targets. Encoding accuracy down to ±0.2μs synchronizes seamlessly with guided munitions.
