1550nm Pulse Laser Soures for DTS
Product Description:
The 1550nm Pulse laser source for DTS of Connet Laser is a pulse 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 lasers are very suitable for the areas of DTS distributed fiber temperature measurement system, laser ranging and optical fiber sensing.
The 1550nm Pulse laser source for DTS of Connet Laser employ separate structure with relatively independent optical and circuit. They have modularized package with 12V DC supply, industry standard DB15 communication port design. The user can control and operate the sources easily by computer. The pulse signal generator is integrated inside the source and the signal synchronization output interface is equipped at the same time. The pulse output can be also achieved by external TTL trigger signal. All modules go through strict environmental test, thus guaranteeing the reliability and stability in a long time. It is very suitable for system integration
