Abstract

A pumped laser cavity includes two parallel glass tubes forming two cavities, a flashlamp for placement in one of the cavities, wherein either the flashlamp or one or more of the parallel glass tubes are doped with one or more of Samarium or Europium.

First claim

What we claim is:

1 . A method of improving the operation of a laser assembly, comprising:
providing a glass element, wherein the glass element comprises two, parallel glass tubes for holding each one of a laser rod or a pumping flash lamp; doping at least one of the two parallel glass tubes of the glass element with one or more of Samarium or Europium, whereby, upon excitation, the doped glass element absorbs at least part of the blue emission spectrum irradiated from the pumping flash lamp when activated.

2 . The method of claim 1 , wherein the laser rod is a Holmium doped laser rod.

3 . The method of claim 1 , wherein the laser rod is a CTH:YAG doped laser rod.

4 . A pumped laser cavity comprising two tubes forming two parallel glass cavities, a flashlamp for placement in one of the glass cavities, wherein the flashlamp is doped with one or more of Samarium or Europium.

5 . A pumped laser cavity assembly, comprising:
two parallel tubes forming two glass cavities; a flashlamp within one of the glass cavities; a laser rod within the other of the two glass cavities; a glass tube surrounding one or both of the flashlamp or the laser rod; wherein the glass tube is doped with one or more of Samarium or Europium.

6 . A method of improving the operation of a laser assembly, comprising:
providing two parallel glass tubes, each having a cavity for holding one of a laser rod or a pumping flash lamp; doping the one or more glass tubes with one or more of: Samarium or Europium, whereby, upon excitation, the one or more doped glass tubes absorb at least part of the blue emission spectrum irradiated from the pumping flash lamp.

7 . The method of claim 6 , wherein the laser rod is a Holmium doped laser rod.

8 . The method of claim 6 , wherein the laser rod is a CTH:YAG doped laser rod.

9 . A pumped laser cavity assembly, comprising:
two parallel glass tubes forming two cavities; a flashlamp within one of the cavities; a Holmium doped laser rod within the other of the cavities; wherein one or more of the glass tubes is doped with one or more of Samarium or Europium.

10 . A method of manufacturing a laser assembly, comprising:
providing a glass element, wherein the glass element comprises two, parallel glass tubes for holding each one of a laser rod or a pumping flash lamp; and, doping at least one of the two parallel glass tubes of the glass element with one or more of Samarium or Europium.

11 . The method of claim 10 , whereby, upon excitation of the doped laser assembly, the doped glass element absorbs at least part of the blue emission spectrum irradiated from the pumping flash lamp.

12 . A multiple cavity laser system comprising:
a controller configured to operate the system; a plurality of glass tubes forming laser cavities, each of the laser cavities including a flashlamp and a laser rod, the plurality of laser cavities also having an output end wherein, when activated by the controller, an output laser beam is emitted from the output end of each of the laser cavities; the controller redirecting the output laser beams along a common optical axis, wherein the output laser beams of the plurality of laser cavities are combined along the common optical axis; and, wherein one or more of the plurality of glass tubes forming the laser cavities are doped with one or more of Samarium or Europium.
