Q -switch is transferred to online lightning of adjustable optic fibre of low -voltage transmission -type pulse width

The utility model discloses a Q -switch is transferred to online lightning of adjustable optic fibre of low -voltage transmission -type pulse width is moved back by two low -voltages and presses the online lightning of transmission -type optic fibre and transfer the Q -switch optical assembly to establish ties, moves back voltage source and a booster power drive with one respectively, and two powers are by a delay control circuit control, and the voltage that both exported is the same with the frequency pulse width of signal, but the signal time have the delay, delay time is at pulse width within range continuously adjustable. The switching time is all extremely short, and representative value 5 -10ns has overcome ordinary power and has closed not dead shortcoming, has improved the extinction ratio of switch, and whole pulse width continuously adjustable in wide region very, has increased the range of application of product, greatly reduce electro -optical crystal operating voltage simultaneously in the design, improved product reliability, the cost is reduced, the Q -switch is transferred to the lightning of optic fibreization, and the integrated level is higher, and it is more convenient to use, all there is huge superiority in structure and performance.
