70mW CW HP
Etern-laser has developed a 1310nm 100mW continuous-wave high-power (CWHP) laser. Its uncooled single-mode edge-emitting directly modulated laser (DML) design combines passive butt-coupling technology and advanced processes to ensure stable output of ≥70mW across - 5°C to 75°C. Low relative intensity noise (RIN), high beam ellipticity, and low power consumption maintain clean, stable optical signals, optimize beam quality for transmission efficiency, and reduce energy costs. Applications include Ethernet, data communications, and optical engines. It offers excellent performance in high-speed, stable network links or as a core optical-engine component, providing efficient, reliable optical solutions.

In photonics and laser technology, devices that manipulate optical signals via the electro-optic effect form the backbone of precision optical systems. Electro-optic phase modulators and electro-optic deflectors are two prominent examples of this device category. As a critical hardware solution for high-speed, high-accuracy laser beam direction control, electro-optic deflectors are widely deployed across industrial and research settings. Below is a detailed overview of their core structure, key performance drivers, and primary use cases.
GYOPTICS 30 W collimated isolator is a highly‑reliable passive optical component optimized for 1064 nm high‑power laser systems. Characterized by low insertion loss and superior backward‑light suppression capability, it effectively blocks reflected light traveling back toward the laser resonator, eliminating back‑reflection‑induced instability and protecting fiber or solid‑state laser sources during long‑term operation.
For 1D optical detection scenarios such as spectrum acquisition, dimensional measurement and optical scanning, area array CMOS/CCD suffer redundant pixels, high cost and slow row readout speed.
Laser pump sources are the core energy input component of solid-state lasers and laser amplifiers, and their performance directly determines the output power, beam quality and service life of the entire laser system. In scenarios such as industrial processing, scientific research experiments and high-end equipment, improper pump source selection will not only result in substandard system performance, but also bring a series of problems such as rapid device degradation and high operation and maintenance costs. This article sorts out the core selection logic and key pitfalls of pump source procurement, and provides selection references based on mature, mass-produced high-reliability products to help purchasers efficiently screen suitable products.
