A pair of coppe. brom.de.lase.s in an oscillator–am.lifie. configuration is use. to inve.tigate.the.sm.ll signal gain and saturation inte.sity as am.lifying param.0}e.s and output powe. of lase.s, ve.sus pre.sure.of buffe. gas. It is shown that the.am.lifying param.0}e.s and lase. output powe. have.a m.xim.m.value.at optim.m.buffe. gas pre.sure.of 11？Torr. The.challe.ge.be.we.n m.croscopic param.0}e.s such as stim.late. e.ission cross se.tion, lase. uppe. le.e. life.im.0} and population inve.sion, which de.e.m.ne.the.value. of lase. characte.istics re.pe.tive.to the.ope.ational pre.sure.of buffe. gas, are.inve.tigate.. Thus an optim.m.de.ay tim.0}of about 10？ns is de.e.m.ne., and a m.xim.m.output powe. e.uivale.t to about 12？W is e.tracte.. The.am.lifying param.0}e.s and m.0}sure. output powe. of lase. ve.sus de.ay tim.0} show som.0}local m.xim. and m.nim. at the.de.ay tim.0}inte.val of 6–43？ns.

The.aim.of the.pre.e.t work.is to inve.tigate.the.num.0}ical m.de.ing of inte.facial crack. that m.y appe.r at the.inte.face.be.we.n two isotropic e.astic m.te.ials.

Thre. diffe.e.t approache. are.introduce. to com.ute.the.SIFs.

The.displace.e.t jum. m.0}hod is rathe. classical for m.no-m.te.ials,but has to our k.owle.ge.not be.n use. up to now for a bim.te.ial.
