2 Micron Single Frequency Fiber Laser Source
Leveraging its expertise in highly doped germanate glass and fibers, NP Photonics offers a 2-um single frequency Ho-doped fiber laser with output powers up to 25 mW. Wavelength operation near 2.05 micron is very attractive for CO2 detection applications. The design of NP Photonics 2-micron short-cavity laser is similar to NP’s Er/Yb and Yb doped phosphate glass fiber laser, which exhibits single-frequency operation with narrow linewidth and excellent frequency-noise properties. A low noise Tm-doped fiber laser pumps the Ho-doped fiber laser – resulting in superior noise properties for the output at 2-micron. An acoustically damped package is used to isolate the DBR laser cavity and results in stable operation over long periods.
Coherent Doppler Lidar and Differential Absorption Lidar (DIALs), working with 2-micron pulsed lasers, make possible detailed measurements of wind, CO2, aerosols, clouds and river flow. Next generation LIDARs require a seed laser source with wavelength tunability, frequency stability, narrow linewidth, efficient operation, compact size, and low thermal load. Recently the development of diode-pumped single frequency fiber lasers has drawn more and more attention due to its narrower linewidth, longer coherence length, multiple wavelength choice, reliability, ruggedness, and compactness. The wide range of operating wavelengths of fiber lasers provide the flexibility for those applications where operation wavelength is vital, such as laser spectroscopy, remote sensing, and coherent laser seeding application.
