用均匀的Q开关红宝石激光束照射在玻璃衬底之间真空沉积的B、C、Mg、Al、Si、Ti、Cr、Mn、Fe、Co、Ni、Cu、Zn、Ge、Zr、Mo、Ag、In、Sn、Sb、Pt、Au、Pb和Bi薄膜。激光脉冲持续时间为15 ns，在直径为6.35 mm的区域内最大能量为5 J。利用相同直径的X切割石英晶片的压电响应研究了应力波。峰值应力呈现为能量影响的函数，并对该现象进行了可能的解释。
Vacuum‐deposited thin films of B, C, Mg, Al, Si, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ge, Zr, Mo, Ag, In, Sn, Sb, Pt, Au, Pb, and Bi in several thicknesses, confined between glass substrates, were irradiated by a uniform Q‐switched ruby laser beam. The laser pulse was 15 ns in duration, with a maximum energy of 5 J in an area 6.35 mm in diameter. The stress waves were studied using the piezoelectric response of X‐cut quartz‐crystal disks of the same diameter. The peak stresses are presented as a function of the energy fluence, with possible interpretations of the phenomenon.
