Only one eye was achieved with deliveries of 0. 5 seconds, 1. 3 watt and a total energy of 52 joules
同時並觀察隅角及視神經盤之組織病理學變化。 -
Laser facilities have been built with the output energy of about a hundred joules at the beginning up to a few mega - joules now and beamline numbers have increased to hundreds. for such facilities, each beamline contains numerous optical elements with enlarged apertures of up to a few tens centimeters and the optical paths extend as long as hundreds of meters
激光裝置的輸出能量從初期的百焦耳級發展到兆焦耳級，其結構規模從小型單路輸出發展到上百路輸出，光學元件數量大幅度增加，光學元件口徑增大到數十厘米，光傳輸距離也從數十米增加到百米。 -
It is not a great deal of energy ? equivalent to about 109 joules per kilogram of hydrogen, much less than the 1015 joules released by the nuclear fusion of the same amount of hydrogen
這能量其實沒有多大游離每公斤的氫需要約109焦耳的能量，遠低於等量的氫進行核融合所釋放出的1015焦耳，所以就算宇宙中只有百萬分之一的氫在恆星內進行核融合反應，也能產生足夠的能量把剩下所有的氫給游離掉。
