Extremely narrowband lasers for precise applications in science and technology
The extremely narrowband laser from OEwaves, available through Soliton GmbH, offer the exceptionally high spectral purity required for cutting-edge high-tech applications. Thanks to the innovative combination of diode lasers and whispering gallery mode (WGM) microresonators, these laser systems achieve linewidths as low as 1 Hz, setting new standards in frequency stability, phase noise, and coherence length.
Technological structure of the extremely narrowband lasers
The laser light is generated by precise coupling into a WGM microresonator, which results in a drastic reduction of frequency noise. extremely narrowband laser They are designed as fiber-coupled systems and, thanks to their compact design, can be easily integrated into existing measurement and production environments. The available wavelengths cover a broad spectrum – from UV (370 nm) through the visible spectrum to the IR range up to 4500 nm.
Applications of lasers in practice
