red light laser

One well-known hologram of that era captured in red laser light a chessboard on which pieces could be viewed from various angles as a viewer shifted position.

一幅当时著名的全息图，是用红色激光拍摄的一个棋盘，当观察者移动位置时，可以从不同的视角观察棋盘上的棋子。

The second laser, which produces red light, then stimulates particular sites to take the second shape. This corresponds to "one" in binary code.

产生红光的第二个激光器刺激某些地方，使其呈现第二种形状，此形状对应于二进制编码中的“1”。

To begin with, the laser palette was rather limited: helium-neon and ruby lasers emitted red light, and others produced invisible infrared.

刚开始时，激光的色彩是相当有限的：氦氖激光器和红宝石发出红光，其他激光器则产生不可见的红外光。
