Introduction
To begin with, the 1535nm Er:Glass laser has become the mainstream light source for civilian, industrial, and special‑purpose applications in the fields of laser ranging, optoelectronic detection, and intelligent sensing. This is primarily due to its core advantages: eye safety, high atmospheric transmittance, and strong anti‑interference capability. Leveraging independently developed Er:Glass gain media and high‑efficiency pump technology, SunFlaser offers a standardized product matrix that covers a full energy range from 20μJ to 10mJ and a full weight range from 6g to 220g. As a result, we provide one‑stop customized light source solutions for micro handheld devices, UAV payloads, industrial inspection, and special optoelectronic systems.

II. Core Technical Advantages of SunFlaser
Genuine Eye Safety: To begin with, the entire series uses 1535nm Er:Glass lasers. The laser energy absorbs fully into the cornea without reaching the retina. Therefore, it meets Class 1 eye‑safe standards and imposes no usage restrictions in open environments.
Military‑Grade Reliability: Furthermore, all products have passed rigorous high‑low temperature cycling, shock, and vibration tests. They maintain stable output across the full ‑40°C to +65°C temperature range. Consequently, they are suitable for vehicle‑mounted, airborne, and field extreme environments.
Full Energy Range Coverage: Additionally, pulse energy ranges from 20μJ to 10mJ, and repetition rates vary from 10Hz to 2kHz. This covers diverse application needs, from short‑range handheld to medium‑range inspection and long‑range detection.
Miniaturised Design: Moreover, we offer designs from ultra‑light 6g packaging to 220g industrial‑grade options, accommodating various installation space constraints. We also support customised package sizes and electrical interfaces.
Low‑Power, High‑Efficiency Drive: Finally, the entire series supports low‑voltage drive (2V/5V/15V options) with high drive efficiency. This significantly reduces overall system power consumption and extends battery‑powered equipment runtime.
