a-BBO
α-BBO is an excellent birefringent crystal material and a negative uniaxial crystal. It has a very large birefringence coefficient and good transmittance from 189nm in the ultraviolet to 3500nm in the mid-infrared. Unlike ß-BBO, due to its centrosymmetric crystal structure, α-BBO does not possess nonlinear optical properties and therefore cannot be used as a nonlinear crystal. α-BBO crystal has good internal quality, low absorption, good mechanical properties and a high damage threshold. Because of its excellent ultraviolet transmission, it is widely used in Glan prism polarizers, birefringent polarizing beam splitters, etc.

A solid-state laser is one of the most common and reliable laser types used in modern industry, medical equipment, and scientific research. Unlike gas or fiber lasers, it uses solid materials as its gain medium to generate stable, high-brightness laser beams. Thanks to its high precision, long lifespan, and compact structure, solid-state lasers have become a mainstream solution for high-precision laser processing and optical systems.
A spatial modulator, most commonly known as a Spatial Light Modulator (SLM), is a core programmable optical device widely used in modern photonics, imaging, and laser systems. It enables precise, dynamic control of light beams, making it indispensable for advanced optical technology and industrial optical equipment.
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.
Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
