Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
81 words
A high efficiency storage laser, comprising: a resonant cavity; means for extracting energy from said cavity; a solid state Tm:LiYF 4 crystal disposed in said cavity; and pump means including an XeBr* mixture and an electron beam exciter for supplying energy to the XeBr* mixture to cause the XeBr* mixture to spontaneously emit sufficient radiation within the absorption band of the Tm:LiYF 4 crystal to cause lasing; and means for supplying the radiation from the spontaneously emitting fluorescer to said crystal.
Claim 2
Dependent Claim
81 words
A high efficiency storage laser, comprising: a resonant cavity; means for extracting energy from said cavity; a solid state Tm:LiYF 4 crystal disposed in said cavity; and pump means including an XeBr* mixture and an electron beam exciter for supplying energy to the XeBr* mixture to cause the XeBr* mixture to spontaneously emit sufficient radiation within the absorption band of the Tm:LiYF 4 crystal to cause lasing; and means for supplying the radiation from the spontaneously emitting fluorescer to said crystal.
Claim 3
Dependent Claim
26 words
A high efficiency storage laser as defined in claim 1, further including a housing containing said resonant cavity, said Tm:LiYF 4 rod and said XeBr* mixture.
