Abstract

The invention discloses a F-P based pulsed laser generator and method. The pulsed laser generator includes a light source, a piezoelectric ceramic mould tunable wavelength filter, a standard comb-shaped filter, a SOA ring laser, a voltage driver, a pulse generator and a spectrum comparison module. The piezoelectric ceramic mould tunable wavelength filter is an F-P chamber, an input end is connected with a light source, two output ends are connected with the standard comb-shaped filter and an input end of the SOA ring laser, and a control terminal is connected with one output end of the voltagedriver; the other output end of the voltage driver is connected with the other input end of the pulse generator; output ends of the standard comb-shaped filter and the SOA ring laser are connected with the spectral comparison module.

Description

technical field [0001] The invention belongs to the field of optical fiber sensing, in particular to an F-P-based pulsed laser generator and method. Background technique [0002] Tunable wavelength filters are the core devices in the field of optical fiber sensing, and there are many types, such as current tuning type, voltage tuning type, piezoelectric ceramic type, etc. Among them, the piezoelectric ceramic tunable wavelength filter has a wide range of applications in the field of optical fiber sensing due to its fast response, no heat generation, large thrust, and high wavelength resolution. For example, it can be used for wavelength demodulation of fiber grating sensors. device. The piezoelectric ceramic tunable wavelength filter utilizes the Fabry-Perot (F-P) cavity structure, and changes the distance between two mirrors (cavity length) through piezoelectric ceramics to achieve variable wavelength output. [0003] The traditional F-P cavity tunable wavelength filter i...
