The swept tunable Laser source is based on advanced electrically pumped VCSEL (Vertical Cavity Surface Emitting Laser) technology. It is an attractive laser for FBG distributed fiber sensing, which synchronous scan rate is up to 200Hz. And the free scan rate can reach 100kHz without synchronous signal output.
The swept source takes advantage of intrinsic features of VCSEL to deliver best-in-class performance, variable scan speed and low signal noise. It features variable power, high stable optical output and comprehensive user interface or RS232 interface to help easy of integration.
