Basic Composition and Pumping Mechanism
The LD (Laser Diode) pumped erbium-doped glass laser is a solid-state laser that uses erbium-doped (Er3+) glass as the gain medium and a semiconductor laser as the pumping source. Its core working principle is as follows
Pumping Source: The laser diode (LD) emits light of a specific wavelength (usually 940 nm). It excites the erbium ions to the metastable high-energy level through direct absorption or indirect energy transfer.
Gain Medium: During the stimulated emission process, the Er3+ ions in the erbium-doped glass transition from the 4I13/2 energy level to the ground state (4I15/2), releasing laser light with a wavelength of approximately 1.535 μm.
Resonant Cavity: It is composed of a high-reflectivity mirror and a partially reflective mirror. Through multiple reflections, it amplifies the photons and forms a coherent laser output.
Characteristics of the Eye-Safe Wavelength Band
The output wavelength of the erbium-doped glass laser is around 1.5 μm, which falls within the near-infrared wavelength band. This wavelength is classified as "eye-safe" (Class 1M) according to international standards. Because the photon energy at this wavelength is relatively low, and it is easily absorbed by the anterior structures of the eyeball (such as the cornea and the lens), it can avoid causing damage to the retina. It is particularly suitable for applications in open environments.

The High Repetition Frequency 1535 nm laser developed and manufactured by ERDI adopts self – developed erbium laser glass and mature bonded – body packaging technology (bonded crystal based on Er: glass and Co: spinel), so it is also known as the 1535 nm micro – chip laser. This laser is Class 1 eye – safe. Because the 1535 nm laser is more easily absorbed by the human eye compared to other lasers, such as the 1064 nm Nd:YAG laser. Currently, our High Repetition Frequency offers a pulsed laser energy of 5 – 70 μJ and a frequency range of 500Hz – 5kHz. Lighter in weight and smaller in size, the 1535 nm laser operates in the infrared range and is widely used as the laser light source for lightweight LiDAR sensors and laser rangefinders.
