RGB White Lasers

RGB White Lasers

Introduction

RGB white lasers seamlessly combine Red (638/640nm, spectral width < 2nm), Green (520nm, spectral width < 2nm), and Blue (450/488nm, spectral width < 2nm) lasers into one. By precisely adjusting the output power of each laser, the RGB white lasers can produce a wide range of colors, including pure white light. Specializing in RGB white lasers, our company focuses on single transverse mode lasers. In addition to our standard RGB laser products, we offer customization options to meet specific requirements.

 

Our product range includes two categories:

RGB Single-Mode Fiber-Coupled White Lasers

RGB Free Space White Lasers
