Product overview
The ERDILRF ER400 is an erbium-glass pulsed laser source for UAV payloads and 1535 nm ranging modules. It delivers 400 µJ pulses at 10 Hz, with a 6 ns optical pulse width measured at FWHM. Applications include coastal and harbour ranging to vessels and structures over water, work with small or low-reflectance targets, and instrument upgrades. Its 35 × 8 × 6.8 mm package weighs 12 g, providing an 8 mm-wide transmitter for integration into optical instruments.
The ER400 combines a TEM00 beam mode with a 0.3 mm raw beam diameter and 7 mrad raw divergence. Optical layouts need space for the collimator. At a fixed 10 Hz while ranging, pump duty is continuous, and the package requires bonding to a heat-spreading surface. Operating temperature is −40 °C to +65 °C, with storage from −55 °C to +85 °C. ERDILRF modules are assembled, aligned, calibrated and accepted in-house in Chengdu.
