1.5um Benchtop Single Frequency Fiber Laser
Product Description:
1.5um benchtop single frequency fiber laser is a turn-key system based on single frequency laser basic module of Connet Laser. It takes special “Optimized Ring Cavity” designed to eliminate the standing wave Spatial Hole Burning phenomenon which appears easily in short linear cavity. It comes with the particular ultra-narrow filter and the polarization controlling technology to realize PM, single longitudinal mode, ultra-narrow linewidth output. It features ultra-narrow linewidth in the kHz range, extremely low RIN and intensity noise and excellent SMSR more than 50dB.
1.5um benchtop single frequency fiber laser is normally with 200mW output power and the other output power can be customized. The center wavelength can be chosen freely in the range of 1535-1575nm, such as the standard wavelengths of ITU.
The benchtop single frequency fiber laser of Connet Laser employs the control system based on microprocessor which has stable property, long lifetime and free maintenance. With a clear interface and easy control, the LCD on the front panel can give a real-time display of the operating state of the output power and temperature. The LCD can also offer warning messages. The lasers are ideal tools for scientific researches.
