GYOPTICS 30W Collimated Isolator Low‑Insertion‑Loss High‑Isolation Solution

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.

The isolator features a central wavelength of 1064 nm. Its maximum insertion loss is only 0.4 dB at 23 °C, minimizing optical power attenuation in forward transmission. Typical peak isolation reaches 35 dB, with a minimum isolation of 28 dB at 30 °C and no less than 20 dB across the full operating temperature range. Minimum return loss hits 50 dB for enhanced suppression of unwanted optical feedback.

The nominal output beam diameter (1/e²) measures 6.5 ± 0.5 mm, with beam circularity over 90 % and M² degradation kept below 10 % for high‑quality beam output. It supports up to 30 W maximum average optical power and 2 mJ maximum pulse energy. For reverse‑power handling, the component withstands 3 W continuous back‑reflection and 10 W transient reverse power for a maximum duration of 3 minutes, delivering robust laser‑source protection.

Input fiber type can be customized according to ordering specifications. The operating temperature covers 10‑50 °C while the storage temperature ranges from 0‑60 °C, enabling stable deployment under variable industrial conditions. Thanks to low insertion loss, high isolation and outstanding reliability, this collimated isolator is well‑suited for laser marking, precision material processing, scientific research and high‑power fiber laser systems.
