【摘要】：高能激光功率高、能量大,造成激光能量計(jì)容易損壞和測(cè)量不確定度增加。圍繞上述問(wèn)題對(duì)國(guó)內(nèi)外現(xiàn)有的幾種高能激光能量直接測(cè)量方法進(jìn)行了比較和歸納,對(duì)各種技術(shù)的優(yōu)點(diǎn)和缺點(diǎn)作了深入的分析,在此基礎(chǔ)上闡述了高能激光能量直接測(cè)量技術(shù)的發(fā)展趨勢(shì)。研究表明,提高熱交換效率是提升高能激光能量計(jì)測(cè)量能力最高效的措施,尤其是在采用體吸收模式和強(qiáng)制熱交換模式的情況下這種效果更加明顯;消除吸收體上溫度梯度對(duì)吸收體材料比熱和溫度傳感器響應(yīng)時(shí)間的影響是提高被動(dòng)吸收型高能激光能量計(jì)測(cè)量準(zhǔn)確度的關(guān)鍵,在水流冷卻型高能激光能量計(jì)和水流直接吸收型高能激光能量計(jì)中消除水流相變的影響和控制水流溫度場(chǎng)不均勻造成的影響則是保證溫度準(zhǔn)確測(cè)量的關(guān)鍵。目前各種高熱交換效率和新體制的測(cè)量方法得到快速發(fā)展和應(yīng)用,系統(tǒng)的測(cè)量能力和測(cè)量準(zhǔn)確度大幅提高,為了適應(yīng)未來(lái)長(zhǎng)時(shí)間測(cè)量需求,能量累積型高能激光能量計(jì)逐漸被功率平衡型高能激光能量計(jì)所替代。
[Abstract]:The laser energy meter is easy to damage and the uncertainty of measurement is increased because of its high power and high energy. Several methods of direct energy measurement of high energy laser at home and abroad are compared and summarized around the above problems, and the advantages and disadvantages of various technologies are analyzed in depth. On this basis, the development trend of direct energy measurement technology of high energy laser is described. The results show that improving the efficiency of heat exchange is the most effective measure to improve the measurement ability of high energy laser energy meter, especially in the case of volume absorption mode and forced heat exchange mode. Eliminating the influence of the temperature gradient on the specific heat of the absorber material and the response time of the temperature sensor is the key to improve the measurement accuracy of the passive absorption high energy laser energy meter. The key to ensure the accurate measurement of temperature is to eliminate the influence of water phase transition and control the influence caused by non-uniformity of flow temperature field in the flow cooling high energy laser energy meter and the flow direct absorption high energy laser energy meter. At present, various measurement methods with high heat exchange efficiency and new system have been rapidly developed and applied, and the measurement capability and accuracy of the system have been greatly improved, in order to meet the needs of the long time measurement in the future, The energy accumulative high energy laser energy meter is gradually replaced by the power balance high energy laser energy meter.
