Description
The 457nm Blue Laser Module (5W) is a high-performance diode-pumped solid-state (DPSS) laser designed for scientific research, optical experimentation, and specialized industrial applications. It delivers a stable 5W blue laser beam at 457nm, generated by pumping a Nd:GdVO₄ crystal with dual 808nm laser diodes. With a fiber-coupled output and compact, rugged construction, this module is ideal for advanced optical setups, including underwater imaging, laser display systems, and material processing. It is intended for use by trained professionals in controlled lab or industrial environments.
Core Features
- Visible Blue Output: 5W of 457nm blue laser light, ideal for high-visibility optical experiments and demonstrations.
- Dual 808nm Pump Design: Two 808nm laser diodes pump a Nd:GdVO₄ crystal for efficient, stable blue light generation.
- Fiber-Coupled Delivery: Ensures precise, low-loss energy transfer to your target optical system.
- Compact & Rugged: Built with a solid copper and aluminum housing for optimal thermal management and long-term durability.
- Research-Ready: Perfect for academic labs, photonics companies, and industrial laser system integrators.
