ATOMIC OSCILLATOR AND METHOD FOR FABRICATING ATOMIC OSCILLATOR
First Claim
1. An atomic oscillator including an Alkaline metal cell in which the Alkaline metal is sealed, a light source which illuminates a laser beam to the Alkaline metal cell, and a light detector which detects light passing through the Alkaline metal cell, wherein the Alkaline metal cell comprises:
- a first member in which a first glass substrate is bonded on a second surface of a first substrate where a first opening part is formed to penetrate from a first surface to the second surface;
a second member in which a second glass substrate is bonded to a fourth surface of a second substrate where a second opening part is formed to penetrate from a third surface to the fourth surface;
a cell internal portion which is formed by the first opening part of the first member and the second opening part of the second member by bonding the first surface of the first substrate in the first member to the third surface of the second substrate in the second member, andan Alkaline metal raw material which is enclosed by the cell internal portion.

Abstract
An atomic oscillator is disclosed, including an Alkaline metal cell, a light source illuminating a laser beam to the Alkaline metal cell, and a light detector detecting light passing through the Alkaline metal cell. The Alkaline metal cell includes a first member, a second member, a cell internal portion, and an Alkaline metal raw material. In the first member, a first glass substrate is bonded on a second surface of a first substrate where a first opening part is formed. In the second member, a second glass substrate is bonded to a fourth surface of a second substrate where a second opening part is formed. The cell internal portion is formed by the first opening part and the second opening part by bonding the first surface to the third surface. The Alkaline metal raw material is enclosed by the cell internal portion.

10. A method for fabricating an atomic oscillator which includes an Alkaline metal cell in which the Alkaline metal is sealed, a light source which illuminates a laser beam onto the Alkaline metal cell, and a light detector which detects light passing through the Alkaline metal cell, said method comprising:
-
forming a first opening part which penetrates from a first surface to a second surface of a first substrate and an second opening part which penetrates from a third surface to a fourth surface of a second substrate, the first opening part and the second opening part having approximately the same shape; forming a first member by bonding a first glass substrate to the second surface of the first substrate where the first opening part is formed, and a second member by bonding a second glass substrate to the fourth surface of the second substrate where the second opening part is formed; inputting an Alkaline metal raw material into the first opening part of the first member or the second opening part of the second member; and bonding a first surface of the first substrate of the first member to a third surface of the second substrate of the second member, wherein a cell internal portion of the Alkaline metal cell is formed by the first opening part of the first member and the second opening part of the second member. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
