1550 nm Eye-Safe Infrared Lasers

1550 nm is the fundamental wavelength of global fiber-optic telecommunications (C-band, minimum fiber attenuation of ~0.2 dB/km). Crucially, 1550 nm is considered "eye-safe" because light is absorbed in the eye cornea and lens before reaching the retina, permitting significantly higher optical powers for automotive LIDAR, military rangefinding, and free-space optical communications.
