Title:
LIGHT CONTROL TRIGGERED LASER
Document Type and Number:
WIPO Patent Application WO/2015/058439
Kind Code:
A1
Abstract:
Disclosed is a light control triggered laser, comprising a saturatable absorber, a light amplifier, a fibre circulator, a fibre optical grating, a pumping module, and main key devices are the light amplifier and the saturatable absorber, wherein the light amplifier is fully pumped and supplies a gain for the entire resonance cavity; and the saturatable absorber supplies a main loss in the resonance cavity. In an initial state, the gain in the cavity is less than the loss, and laser emission cannot be formed. A single trigger turn-on light pulse is injected into the resonance cavity, thus turning on the light control triggered laser. In a laser turn-on state, a single trigger turn-off light pulse is injected into the resonance cavity, thus turning off the laser. When the time of light pulse triggering is over, the laser recovers to a state of not being triggered to turn on, the gain in the cavity is less than the loss, a turning-off state of the laser continues to be maintained, so as to completely realize the turning-off of the light control triggered laser. The light control triggered laser of the present invention has a simple and compact structure without connecting a light control optical switch outside the cavity, and therefore, the entire structure is more stable.
