1389nm Narrow linewidth laser
Precilasers has launched a single-frequency Raman fiber amplifier with an ultra-wide wavelength range of 1120-1700 nm, filling the gap in emission wavelengths of rare-earth ion-doped fiber lasers. This series of single-frequency Raman amplifiers, based on Raman amplification technology, boasts a maximum output power of up to 30 W. Its all-polarization-maintaining, all-fiber structure ensures the laser features a compact design, excellent long-term stability, and maintenance-free operation. Meanwhile, it guarantees extremely low intensity noise and phase noise of the output laser. With characteristics such as high power, low-noise amplification, and ultra-fast seed cut-off protection, this amplifier meets the demand for lasers with special wavelengths in applications like laser atomic cooling and laser spectroscopy.
