In Fig. 1, through 45 ° of beam steering speculum 19 break-ins, light beam directing mirror 18 is divided into two bundles with seed light less than the seed light of 100 femtoseconds for the pulse recurrence rate 80MHz of titanium jewel oscillator 20 output, pulse duration.10% transmitted light is received by optical-electrical converter 17, and other 90% reverberation is prepared to be injected in the vibration chamber through behind the isolator 16.10% the transmission seed light that optical-electrical converter 17 will receive is converted to the electric impulse signal that repetition rate is 80MHz, be input to general gram youngster box control power supply 13, frequency divider in the Pockers cell control power supply 13 carries out frequency division to the signal of telecommunication of 80 megahertzes, produces 2 road TTL signals of telecommunication of 1K hertz.One tunnel green glow pumping source 1 that is used for trigger amplifier, the light beam of green glow pumping source 1 output through condenser lens 2, focus of the light beam in the titanium gem crystal 4, makes the population of titanium jewel reverse.Upper surface plane mirror 6, lower surface plane mirror 8, unfold angle plane speculum 15, preceding concave mirror 3, back concave surface mirror 5 and constituted titanium jewel regenerative amplification chamber.Another road is sent in the electric pulse modulating device 10, be subjected to the modulation of binary digital signal after, Pockers cell 9 is controlled.Electric pulse modulating device 10 is by connecting and composing with 10-1, shift register 10-2, d type flip flop 10-3, computer 10-4, circuit board 10-5, the work of electric pulse modulating device 10 is subjected to the control of computer 10-4, computer 10-4 is transported to digital signal among the shift register 10-2, and d type flip flop 10-3 sequentially takes out binary data bit from shift register 1-2.When binary data is 1, export a high level, binary data is 0 o'clock, exports a low level, shift register 10-2 current data position becomes next binary digit automatically.Two path signal through with door 10-1 after export, obtain the TTL signal of telecommunication of having modulated by digital signal.This signal is divided into two-way, and the delayer of being controlled power supply 13 by Pockers cell loads τ respectively
1And τ
2Time delay after, trigger the high-voltage switch gear of Pockers cell 9, the seed light of controlling Pockers cell 9 respectively injects and pour out in the chamber.Light beam directing mirror 18 is input to 90% incident laser in isolator 16 and the half-wave plate 14, converts the polarization direction of light beam to vertical polarization by horizontal polarization.Again through the transmitted light of 90/10 beam splitter 12,10% by guide light reflection mirror 11, incide on the film polarizer 7.The seed light that film polarizer 7 is vertical with the polarization direction reflexes in the Pockers cell 9.Because this moment, Pockers cell 9 was at the Zero-bias working state, was equivalent to quarter-wave plate, light pulse comes and goes Pockers cell 9 once, and the polarization direction half-twist becomes level, sees through film polarizer 7 and enters in the amplifier; Before laser pulse in being injected into amplifier returns Pockers cell 9 for the first time, through postponing τ
1The TTL triggering signal become high level, trigger the high-voltage switch gear of Pockers cell 9, add quarter-wave voltage (making the optical path difference between its o light and e light increase quarter-wave voltage again) for Pockers cell 9, Pockers cell 9 becomes half-wave plate, laser pulse is through Pockers cell 9 round trips, and its polarization direction remains unchanged, and light pulse is able to vibration back and forth in amplifier, repeatedly amplified, and can not reflected the vibration chamber by film polarizer 7.Simultaneously, during laser pulse amplified, the polarization direction that is injected into the seed optical pulse in the Pockers cell 9 can not change yet, thereby reflects enlarged cavity by film polarizer 7, no longer receives the injection of seed light in the enlarged cavity.When the pulsed laser energy that amplifies reaches capacity, postpone τ in the vibration chamber
2The TTL signal of telecommunication trigger Pockers cell 9, make it return to the Zero-bias working state, the polarization direction of the laser pulse that amplified is changed into vertical by level, make this pulse from amplifier, export through film polarizer 7, guide light reflection mirror 11 and beam splitter 12.Obtain the amplification of being modulated by digital signal laser pulse sequence.
