Abstract
Abstract A laser utilizing a unique assembly for mounting a Brewster angle window. The mounting assembly includes an elongated annular member having a transverse slot at the appropriate Brewster angle to the plane perpendicular to the axis of the annular member. A rectangular window is held in place in the slot by the tension of a leaf spring. The mounting assembly may then be inserted in place at either the anode or cathode ends of the laser and permanently held in place without introducing any stresses in the window or affecting its alignment.

Claim 1
Independent Claim
55 words
A Brewster window mount comprising: an elongated annular sleeve having a transverse slot disposed at the Brewster angle for supporting a Brewster window mounted within said slot; a Brewster window disposed within said slot; and a leaf spring disposed within said transverse slot and adjacent to said Brewster window for maintaining said window in place.
Claim 2
Dependent Claim
55 words
A Brewster window mount comprising: an elongated annular sleeve having a transverse slot disposed at the Brewster angle for supporting a Brewster window mounted within said slot; a Brewster window disposed within said slot; and a leaf spring disposed within said transverse slot and adjacent to said Brewster window for maintaining said window in place.
Claim 3
Dependent Claim
82 words
A laser having an improved Brewster window mount, comprising: a laser discharge tube having an optical axis; an elongated annular sleeve having a transverse slot at the Brewster angle for supporting a Brewster window mounted within said slot, said sleeve being at one end of said laser discharge tube and optically aligned therewith; a Brewster window disposed within said slot; and a leaf spring disposed within said transverse slot and adjacent to said Brewster window for maintaining said Brewster window in place.
