Each pulse control signal.Simultaneously due to the distance between 130 road Zhong Mei light source module 130 of the road M light source module and controller 120
It is not necessarily identical, therefore since the optical path difference of distance generation is also not necessarily identical between every road light source module 130 and controller 120.
In this way, to obtain the second moment of each of corresponding each pulse control signal also not necessarily identical for each seed source laser 131.
For the seed source laser 131 of every road light source module 130, obtained at corresponding each second moment
Corresponding each pulse control signal, each seed source laser 131 based on the waiting time in each pulse control signal, that
The third moment can be waited until from the second moment for obtaining each pulse control signal without executing operation.
As some embodiments, to guarantee execution that each seed source laser 131 can synchronize to transmitting laser arteries and veins
Line delay is rushed in, in order to control the synthesis mode of subsequent each laser pulse by being delayed, then each kind can be made
Component laser 131 waits until that the third moment is synchronization according to waiting time, i.e. the corresponding M of the road M light source module 130
The third moment is synchronization.
Therefore, to guarantee that M third moment is synchronization, if M the first moment are at least partially synchronization, that
When being contemplated that each of each pulse control signal of transmitting first in the waiting time being arranged in each pulse control signal
Carve the influence of the optical path difference generated with the light path of institute's conduct after the transmitting of each pulse control signal.
For example, i-th of pulse control signal is that the A moment emits and the optical path difference of i-th of pulse control signal is 0, i+1
A pulse control signal be to send and compared to i-th pulse control signal 10ns after the A moment B constantly at the first moment
Optical path difference is 10ns.It, can be by i+1 pulse control therefore when the waiting time of i-th of pulse control signal being set as 50ns
The waiting time of signal processed is set as 30ns, ensure that in this way third moment that i-th of pulse control signal waits until and
The third moment that i+1 pulse control signal waits until is identical, wherein i is the positive integer no more than N.
And also to guarantee that M third moment is synchronization, if M the first moment are synchronization, then being arranged
It can the light path of institute's conduct generates after each pulse control signal transmitting light path when waiting time in each pulse control signal
The influence of difference.
Also for example, the optical path difference of i-th of pulse control signal is 0, compared to i-th arteries and veins of i+1 pulse control signal
The optical path difference of punching control signal is 10ns.It, can be by therefore when the waiting time of i-th of pulse control signal being set as 50ns
The waiting time of i+1 pulse control signal is set as 40ns, thus it is also ensured that i-th of pulse control signal waits until
Third moment for waiting until of third moment and i+1 pulse control signal it is identical.
What is needed is bright, is also used as some embodiments, if original at the time of M the first moment of definition are different
Because being the influence in order to eliminate optical path difference, then setting waiting time can not had in each pulse data signal, and can
Delay duration and pulse signal only is arranged in each pulse data signal.Since main controller is sent each at each first moment
The optical path difference of each pulse control signal can be eliminated when pulse control signal, in this way, M seed source laser 131 can
To obtain M pulse control signal and M seed source laser 131 correspondingly the M of synchronization the second moment
In each seed source laser 131 can be according to the direct trigger of pulse extension duration.
Also for example, i-th of pulse control signal is that the A moment emits and the optical path difference of i-th of pulse control signal is 0, that
Compared to the optical path difference of i-th of pulse control signal it is 10ns in i+1 pulse control signal, therefore i+1 can be defined
A pulse control signal be the first moment be the A moment before B moment of 10ns send.I-th of pulse control is ensured that in this way
Signal processed and i+1 pulse control signal are respectively sent to corresponding two seed source lasers at same second moment
131。
In this present embodiment, each seed source laser 131 is being waited based on pulse delay duration from each third moment
When to four moment, each seed source laser 131 just can also drive according to pulse signal in each pulse control signal
And generate waveform source laser pulse all the way identical to the pulse signal, and by optical fiber by this all the way source laser pulse export to
N grades of amplifiers 132.
Can also be understood that, for each seed source laser 131, due in each pulse control signal etc.
The not substantial signal of strong point when duration and pulse delay, therefore each seed source laser 131 can be at each 4th
It carves to execute in each pulse control signal and has the pulse signal part of substantial signal, swash so that corresponding source all the way can be exported
Light pulse.
Can also also be understood that, be arranged each pulse control signal pulse delay duration can based on it is subsequent can be as
What is combined the road M laser pulse.For example, if by the road M laser pulse be superimposed to increase energy intensity and mean power when, can
It sets identical for each pulse delay duration or intersects；If arranging the road M laser pulse to increase energy intensity and pulsewidth,
It can set not identical for each pulse delay duration and not intersect；If the road M laser pulse is superimposed and is arranged to increase energy
When intensity, mean power and pulsewidth, it is a part of not identical each pulse delay duration can be set to and is not intersected, and it is another
Portion is then identical or intersects.
