Precision & Reliability for System Integration

Choosing the right laser diode involves more than matching a wavelength. Power, beam quality, operating mode, and thermal management are critical. Our laser diodes are specified with complete characterization data and tight tolerances, giving engineers the confidence to design systems around real performance, not just nominal values.

Whether you're building a fiber laser, a medical platform, or a custom industrial machine, you'll find the right diode in our catalog. And if you don't, we'll build it for you.

The Critical Role of Wavelength Stability

A standard laser diode's wavelength shifts with temperature. For many applications this is fine, but for spectroscopy, sensing, or pumping at narrow absorption peaks (like 976nm), this drift reduces efficiency and reliability. That's why we offer a huge range of VBG (Volume Bragg Grating) stabilized laser diodes, which lock the wavelength to within ±0.5 nm across the entire operating range.
