专利汇可以提供Gas dynamic laser having shutter doors专利检索，专利查询，专利分析的服务。并且A gas dynamic laser is shown wherein gases containing constituents necessary to obtain a lasing action are passed through a nozzle array and directed into a lasing cavity and through a diffuser to an exit. An opening is located on each side of said lasing cavity with a shutter box outside of said cavity having a shutter door for opening or closing said opening. A mirror box is located behind each shutter box and contains a mirror. These mirros are aligned with the openings in the lasing cavity with each door positioned between an opening and a mirror. Another outlet opening is positioned downstream of the first opening which provides an outlet opening for a laser beam. A shutter box is located around this opening and also houses a shutter door for opening and closing said opening. The mirror box which extends behind this shutter box includes opening means for permitting the output beam to pass through an aerodynamic window to atmosphere. Actuating means are provided for rapidly opening and closing said shutter doors. Bearing means including recirculating balls are located on the top and bottom of each shutter door to rise in tracks at an angle to the sealing surface on the laser device. Vacuum means are provided to reduce the pressure in the shutter box and mirror box independently of the pressure in the lasing cavity.，下面是Gas dynamic laser having shutter doors专利的具体信息内容。

权利要求

1. In a gas dynamic laser the combination comprising: means for providing a lasing gas, a housing forming a lasing cavity, a nozzle array for introducing a gas containing constituents necessary to obtain a lasing action into said lasing cavity, diffuser means for directing gas flow from said cavity, said housing around said lasing cavity having a first opening on one side thereof and a second opening on the other side, a first box means located on the exterior of said housing around said first opening, a second box means located on the exterior of said housing around said second opening, a mirror positioned in each box means in alignment with said two openings, a third opening located in said housing downstream of said other openings, said third opening being positioned to receive an output beam from said mirror in said second box means, said third opening also being connected to said first box means, a fourth opening in said first box meAns aligned with said third opening to permit the output beam to pass to the exterior of the first box means, an aerodynamic window connected to said fourth opening, a shutter door being located in said first and second box means adjacent each of said openings to reduce the volume necessary to be evacuated by the diffuser means during the start of flow through the diffuser means and to control the opening and closing of said openings to start and stop the lasing action, one shutter door in said first box means being located between the mirror and first opening, one shutter door being located in said first box means between said third opening and aerodynamic window, one shutter door in said second box means being located between the mirror and second opening, means for sliding each door at an angle to the plane of the opening in said housing so that a shutter door is rapidly moved to and from its closed position, means for actuating said shutter doors to move them between an open and closed position, means for reducing the pressure in both the first and second box means when the doors are closed to balance the pressure on both sides of the doors in preparation for starting the lasing action.
