Abstract
Abstract A solid state laser including a plurality of plate like lasable elements in an array on a common optical axis. There are two different plate like elements, arranged in an alternating pattern, each containing a lasing ion which lases at a wavelength that is different from the wavelength of the other. The lasing ions and host materials are chosen so that there are two distinct spectral regions in which the lasing output of one plate element is not strongly absorbed by the other plate element.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
146 words
A laser structure which comprises, in combination: a first plurality of solid state, plate like lasable elements having a first absorption region of white pump light and an output beam at a first wavelength, said first plurality of elements being aligned in a spaced apart array along a common optical axis; a second plurality of solid state, plate like lasable elements having a second absorption region of white pump light and an output beam at a second wavelength, said second plurality of elements being aligned in an alternating, adjoining pattern with said first plurality of elements along said common optical axis and said first and second pluralities of elements being such that neither strongly absorbs said first and second output beam wavelengths; means for furnishing white pump light to said first and second elements; and end mirror means for said array of first and second elements.
Claim 2
Dependent Claim
146 words
A laser structure which comprises, in combination: a first plurality of solid state, plate like lasable elements having a first absorption region of white pump light and an output beam at a first wavelength, said first plurality of elements being aligned in a spaced apart array along a common optical axis; a second plurality of solid state, plate like lasable elements having a second absorption region of white pump light and an output beam at a second wavelength, said second plurality of elements being aligned in an alternating, adjoining pattern with said first plurality of elements along said common optical axis and said first and second pluralities of elements being such that neither strongly absorbs said first and second output beam wavelengths; means for furnishing white pump light to said first and second elements; and end mirror means for said array of first and second elements.
Claim 3
Dependent Claim
23 words
The laser structure of claim 1 which is further defined by said alternating first and second elements being in contact with one another.
Claim 4
Dependent Claim
33 words
The laser structure of claim 2 which further includes a transparent liquid, between said contacting first and second elements, that matches the index of refraction of one of said first and second elements.
Claim 5
Dependent Claim
49 words
The laser structure of claim 1 which is further defined by said first and second elements being inclined at an angle with respect to said optical axis and said means for furnishing white pump light to allow passage of a majority of pump light through both of said elements.
