According to gas discharge principle, the most breakdown formation of gas in described gas excitation system 300
Arc discharge is luminous.In arc discharge, also gas is had while luminescence heat effect, thus be conducive to
Gas ionization in described gas excitation system 300.
And after the gas in described gas excitation system 300 is ionized, in described gas excitation system 300
Gas can form plasma, therefore its breakdown voltage can reduce further.So when described exciting gas
After gas in source 300 is ionized, it is only necessary to maintain power supply, described gas excitation system 300 can be maintained
Luminous.So in the present embodiment, starting to export described external trigger voltage when starting described laser instrument,
Output is stopped after being lit in described gas excitation system 300.
It should be noted that in the present embodiment, use described metal shell 410 as external trigger electrode
Way is only an example, in other embodiments of the invention, it is also possible to uses and is wound in described gas excitation system
Outer wire is as other forms such as external trigger electrodes.
So with continued reference to Fig. 2, described laser instrument also includes power supply 500, for swashing to described gas
Encourage source 300 and electric energy is provided.
Concrete, to institute after the described power supply 500 gas ionization in described gas excitation system 300
Stating gas excitation system 300 and provide lasting electric energy, described external trigger voltage 420 is at described power supply 500
Stop providing described external trigger electricity to described external trigger electrode after described gas excitation system 300 provides electric energy
Pressure.
In the present embodiment, described gas excitation system 300 is xenon lamp, when after the gas ionization in described xenon lamp,
Conducting electric current can be formed in xenon lamp.Therefore it is lit when described xenon lamp, after forming conducting electric current in xenon lamp,
Described external trigger voltage 420 stops providing described external trigger voltage to described metal shell 410.
Additionally, described gas excitation system 300 also includes internal trigger electrode, described power supply 500 and institute
State internal trigger electrode to be connected, be additionally operable to provide internal trigger voltage so that described gas to described internal trigger electrode
The gas ionization of driving source.Concrete, described internal trigger voltage is more than 10KV, in the present embodiment, described
Internal trigger voltage is about 16KV.
Concrete, described gas excitation system 300 is xenon lamp, is provided with filament 501 in described xenon lamp, described
The filament 501 of xenon lamp is internal trigger electrode.Filament 501 phase of described power supply 500 and described xenon lamp
Even, when the gas in described xenon lamp is ionized, it is positioned between the filament 501 at xenon lamp two ends and can form conducting
Electric current, power supply 500 is powered to described xenon lamp by the filament 501 of described xenon lamp.
It should be noted that in order to improve the success rate that described xenon lamp is triggered, it is to avoid the most repeatedly to institute
State xenon lamp load high pressure and cause power supply load excessive, in the present embodiment, described external trigger power supply 420 to
While described external trigger electrode provides external trigger voltage, described power supply 500 is to described internal trigger electricity
Pole provides described internal trigger voltage.It is to say, described external trigger power supply 420 is same with described power supply
Time respectively described metal shell 410 and described xenon lamp filament load external trigger voltage and internal trigger voltage,
Carried out by external trigger and internal trigger simultaneously, to improve the success rate lighting xenon lamp, reduce described power supply electricity
