Description
Technical field
The present invention relates to mode locked fiber laser and frequency comb field of measuring technique, relate in particular to a kind of annular chamber mode locked fiber laser that can produce high repetition frequency laser.
Background technology
Optical frequency com is used for realizing the measurement extremely accurate to optical frequency, produced by mode-locked laser, and be a kind of ultra-short pulse laser.Two of the light pulse of mode-locked laser emission are characterized as the key that produces good optical frequency com.
First feature is repetition rate (frequency interval).Mode-locked laser is with the repetition rate launch pulse sequence, the frequency spectrum of this pulse train light is not to extend continuously to both sides centered by carrier frequency, but form many discrete frequencies, and this frequency distribution is the spitting image of broach, and frequency interval equates with the repetition rate of laser.This frequency interval can be stablized by long realization of phase lock circuitry control chamber.The frequency interval of optical frequency com should be more than 250MHz according to application demand, even reaches hundreds of GHz.
Second feature is impulse phase.Pulse envelope is with respect to carrier wave generation micro-displacement, cause the pulse generation slight change, the peak value of pulse envelope can occur simultaneously with the carrier wave crest of correspondence, and other crests that also can be displaced to carrier wave occur simultaneously, and this side-play amount is called the carrier-envelope phase skew of pulse.It is exactly frequency shift (FS) corresponding to broach that this drift is reflected in frequency domain, i.e. null offset.This null offset can be determined and stablizes by the group velocity dispersion of control in the laser.
Can pass through fundamental frequency-frequency multiplication beat frequency method to laser carrier envelope phase drift and survey and lock, based on solid state laser particularly the frequency interval of the frequency comb of ti sapphire laser reach more than the 1GHz.
