    Product Description:

    The 1550nm pulsed laser source for DTS of Connet Laser is a pulsed fiber laser source with high efficiency based on the 1550nm wavelength which is safe to human eyes. The new ns class pulse drive circuit has stable pulse and tiny distortion. The optimized low noise Er-doped fiber amplifiers realize high peak power and ns class pulse output laser. These laser sources are very suitable for the areas of distributed fiber temperature measurement system (DTS), laser ranging and optical fiber sensing.

    The 1550nm pulsed laser source for DTS of Connet Laser employs the separate structure with relatively independent optical path and circuit. The source has modularized package with wide voltage supply and the industry standard DB15 communication port design. The user can control and operate the laser source easily by computer. The pulse signal generator is integrated inside the source and the synchronization signal output interface is equipped at the same time. The pulse output also can be achieved by external TTL trigger signal. All modules go through the strict environmental tests to guarantee the reliability and stability in a long time. This laser source is very suitable for system integration
