Product Description

The MINI-100 is ERDI’s ultra-compact 1535 nm eye-safe microchip laser, built on co-doped Er:Yb phosphate glass and LD pumping. It delivers ≥100 µJ pulse energy, 3.5 ns pulse width and 1–10 Hz repetition rate in a package measuring only 14.5 × 6.3 × 4.37 mm³ with a mass of 2.5 g, making it an ideal core for micro and small laser rangefinders, compact LiDAR units and integrated electro-optical payloads. 

The raw beam diameter is about 0.3 mm with ≤10 mrad divergence and TEM₀₀ beam mode, providing a clean, near-Gaussian output that is easy to collimate or couple into downstream optics. The device operates from a 2 V drive with a current of 12 A, and the specified pulse stability is 10%, giving a good balance between energy density and electrical input in tightly constrained platforms. 

Environmentally, MINI-100 is designed for demanding field conditions: the operating temperature range is −40 °C to +65 °C, storage is −55 °C to +85 °C, and both impact and vibration performance meet MIL-STD-810G test standards (1500 G, 0.5 ms shock; 20–2000 Hz / 20 G vibration). The rated service life is ≥10 million shots, supporting long-term use in duty-cycle-limited rangefinder and LiDAR applications rather than lab prototypes. 

From a system perspective, MINI-100 is the transmitting core in a 1.5 µm Time-of-Flight ranging chain: an LD-pumped erbium-doped glass cavity generates a narrow nanosecond pulse, which is collimated by the external optics and sent to the target; on return, an InGaAs/APD receiver and high-speed TDC provide centimetre-level accuracy over distances from hundreds of metres to tens of kilometres, depending on the full system design. The 1.5 µm eye-safe band offers low atmospheric loss, strong penetration in fog and rain and good resistance to background light, which is why it is widely used in military fire-control rangefinders, UAV pods, airborne/spaceborne LiDAR and industrial structural monitoring. 

ERDI positions MINI-100 as the microjoule-level product in its erbium-glass portfolio: extremely small and light, tailored for direct modular integration onto the circuit boards of micro and small rangefinders. For applications requiring ranges beyond roughly 15 km, ERDI’s millijoule-class erbium-glass lasers with much higher single-pulse energy are recommended; MINI-100 is optimised instead for size, weight, power and integration density in compact systems. 

With its combination of Class 1 eye safety, ≥100 µJ energy, 3.5 ns pulse width, micro-size package, MIL-STD-810G robustness and erbium-glass technology, MINI-100 is a strong choice as a 1.54 µm laser source for board-level rangefinder modules, compact LiDAR, UAV / UGV payloads, handheld rangefinders and precision industrial sensing equipment.
