Device and method.
Background technique
The main function of image intensifer is the system for carrying out energy amplification to light beam, and major function is to generate and can reach
It is a kind of laser amplifier device being widely used using the power or pulse energy of required light beam.
Laser amplifier technology is broadly divided into two kinds of regenerative amplifier and linear multi-way amplifier.Regenerative amplifier is to utilize
One resonant cavity repeatedly amplifies laser pulse progress back and forth, is reaching certain peak by the introducing of laser beam pulse

Purpose, the optimum pulse mean power that laser pulse can reach is amplified by regenerative amplifier, is in general existed
Ten watts or so.Light beam is distinguished when linear multi-way amplifier is processes single or multiple across amplification medium by arrangement laser beam
Single or multiple amplifications are carried out, the mean power that the light beam amplified by linear amplifier can reach can generally compare
The average output power that regenerative amplifier can reach is big, as hectowatt, kilowatt or myriawatt rank.It is high-power in solid or optical fiber
In laser application, linear amplifier is in the application for generating high power-beam than wide.In solid laser amplifier, using more
Cheng Fang great can achieve higher output power.Therefore, linear Multi-pass laser amplifier has attracted much attention.
General single multi-way amplifier, more is to arrange two Cheng Fang great, hence it is evident that amplified more than two Cheng Fang great
Journey is more difficult accomplished in simple amplifier installation.Main cause is the amplification of two journeys or more, is difficult the light that will amplify
Shu Duoci is introduced into effective pumped region of the same amplification medium, such as keep lesser angle in end-pumping and and pump
Pu region is effectively overlapped, and reaches higher efficiency of amplitude.Using plate as amplifier medium profile pump, guidance laser exists one kind
By the multiple laser amplifier being rubbed open back and forth by effective magnification region in lath, most of is one way or two journeys by office
Effective pumped region in portion, partly solves the demand of high power amplifier.However, most lath amplifying devices can be defeated
Laser beam quality out will not be fine, or the drawback for having the overall efficiency of amplifying device not high.
Sterling Backus et al. elaborates a kind of three mirror energy of use in United States Patent (USP) US5,644,424
Enough methods that multiple circulation amplification is effectively carried out to laser beam.However, method used in these patents is defeated to what is more increased
For the requirement of light power, due to the limitation of the pumping fuel factor using single amplification medium, compares and be difficult to reach higher
Power.Multi-way linear amplifier in relation to previously other inventions can refer to United States Patent (USP) US3,365,671 or US4,156,
852 etc..
It is therefore desirable to have the linear multi-way of bigger output power is amplified, it can reach and amplify using required output characteristics
