Abstract
Abstract A hollow mirror seat, insertable into the end of a laser tube, has a first portion having a first length and a first outside diameter close to the inside diameter of the laser tube. A second portion of the mirror seat has a second length and a second outside diameter smaller than the inside diameter of the laser tube. A portion of the second length has a region of reduced wall thickness around its entire circumference.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
A protected internal laser mirror adjustment apparatus, insertable into a laser tube, including: a hollow mirror seat completely insertable into the end of a laser tube, said mirror seat having a first portion of a first length and a first outside diameter closely matched with the inside diameter of said laser tube, and having a second portion of a second length and a second outside diameter smaller than said first outside diameter for attachment of a mirror, means in said second length, for facilitating the deformation of at least the portion of said second length of said mirror seat to which said mirror is attached, thereby adjusting said mirror off of its normal axis.
Claim 2
Dependent Claim
114 words
A protected internal laser mirror adjustment apparatus, insertable into a laser tube, including: a hollow mirror seat completely insertable into the end of a laser tube, said mirror seat having a first portion of a first length and a first outside diameter closely matched with the inside diameter of said laser tube, and having a second portion of a second length and a second outside diameter smaller than said first outside diameter for attachment of a mirror, means in said second length, for facilitating the deformation of at least the portion of said second length of said mirror seat to which said mirror is attached, thereby adjusting said mirror off of its normal axis.
Claim 3
Dependent Claim
123 words
In a laser having a protected internal mirror adjustment apparatus, said adjustment apparatus including: a laser tube having a first inside diameter, a hollow mirror seat completely insertable into the end of a laser tube, said mirror seat having a first portion of a first length and a first outside diameter closely matched with the inside diameter of said laser tube, and having a second portion of a second length and a second outside diameter smaller than said first outside diameter for attachment of a mirror, means in said second length, for facilitating the deformation of at least the portion of said second length of said mirror seat to which said mirror is attached, thereby adjusting said mirror off of its normal axis.
Claim 4
Dependent Claim
123 words
In a laser having a protected internal mirror adjustment apparatus, said adjustment apparatus including: a laser tube having a first inside diameter, a hollow mirror seat completely insertable into the end of a laser tube, said mirror seat having a first portion of a first length and a first outside diameter closely matched with the inside diameter of said laser tube, and having a second portion of a second length and a second outside diameter smaller than said first outside diameter for attachment of a mirror, means in said second length, for facilitating the deformation of at least the portion of said second length of said mirror seat to which said mirror is attached, thereby adjusting said mirror off of its normal axis.
Claim 5
Dependent Claim
94 words
A protected internal laser mirror adjustment apparatus, insertable into a laser tube, including a hollow mirror seat completely insertable into the end of a laser tube, said mirror seat having a first portion of a first length and a first outside diameter closely matched with the inside diameter of said laser tube, and having a second portion of a second length and a second outside diameter smaller than said first outside diameter for attachment of a mirror, a portion of said second length having a region of reduced wall thickness around its entire circumference.
Claim 6
Dependent Claim
94 words
A protected internal laser mirror adjustment apparatus, insertable into a laser tube, including a hollow mirror seat completely insertable into the end of a laser tube, said mirror seat having a first portion of a first length and a first outside diameter closely matched with the inside diameter of said laser tube, and having a second portion of a second length and a second outside diameter smaller than said first outside diameter for attachment of a mirror, a portion of said second length having a region of reduced wall thickness around its entire circumference.
Claim 7
Dependent Claim
103 words
A laser tube having a protected internal mirror adjustment apparatus, including: a laser tube having a first inside diameter, a hollow mirror seat insertable into the end of said laser tube, said mirror seat having a first portion of a first length and a first outside diameter, said first outside diameter being such that a vacuum seal may be formed between it and said laser tube, and having a second portion of a second length and a second outside diameter smaller than said first outside diameter, a portion of said second length having a region of reduced wall thickness around its entire circumference.
Claim 8
Dependent Claim
103 words
A laser tube having a protected internal mirror adjustment apparatus, including: a laser tube having a first inside diameter, a hollow mirror seat insertable into the end of said laser tube, said mirror seat having a first portion of a first length and a first outside diameter, said first outside diameter being such that a vacuum seal may be formed between it and said laser tube, and having a second portion of a second length and a second outside diameter smaller than said first outside diameter, a portion of said second length having a region of reduced wall thickness around its entire circumference.
