Detailed Description
Applications  Coherent detection  Spectral analysis  Laser radar  Microwave photonics research  Optical measuring instrument  Seismographic  Fiber Optical Hydrophone Features  Narrow Linewidth: < 30KHz  Excellent long term stability of wavelength  lower cost solution by semiconductor laser  High Output Power  Meet the requirements of ITU-T wavelengths  Module, Benchtop is available  Easy to operate:RS232, RS485 is available Description The key component of the optical source is external cavity semiconductor laser. The output spectrum line has the characteristic of narrow linewidth and long coherent length. The product is comparable to narrow linewidth fiber lasers, and it is widely used in optical fiber sensing and other fields. Based on the structural characteristics of semiconductor lasers, it also has the unexampled cost advantage against fiber lasers. A proprietary ATC (automatic temperature control circuit) and APC (automatic power control circuit) circuit insure the stability output power. Its unique structure can ensure its excellent long-term stability of wavelength Desktop or module structure can be optional.
