VFLS Series 1550nm Pulsed Laser Soures for DTS

OVERVIEW

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 lasers are very suitable for the areas of DTS distributed fiber temperature measurement system, laser ranging and optical fiber sensing. 


The 1550nm pulsed laser source for DTS of Connet Laser employs separate structure with relatively independent optical and circuit. It has modularized package with 12V DC supply, industry standard DB25 communication port design. The user can control and operate the source 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 the strict environmental tests, thus guaranteeing the reliability and stability in a long time. It is very suitable for system integration.
