Title: Temperature controller for optical element and laser oscillator
Inventor: TSUNEKANE MASAKI
IPC: H01S3/02
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized temperature controller which can control the temperature of an optical element in a high-temperature region and has temperature controllability and temperature stability by controlling the temperature of a supporting body having a plurality of components welded to each other with a brazing material having a melting point of a specific temperature or higher and to obtain a laser oscillator having excellent output stability. SOLUTION: The heat generated by a resistive heat generating wire 310 reaches an optical element 330 inserted into a through hole 343a after the heat is transferred to a supporting section 343 through a heat transferring section 341. The heat is further transferred to a Peltier element 320 through a heat transferring section 342. While the heat generated from the wire 310 reaches the Peltier element 320, a temperature gradient which is higher on the wire 310 side and lower on the element 320 side is generated in a holder 340, because the heat is radiated. Therefore, the safety of the Peltier element 320 itself can be secured even when the temperature of the optical element 330 exceeds 200 deg.C, because the temperature of the element 320 can be maintained at a value lower than the melting point of the bond used in the element 320 by contriving the shape of the holder 340.

Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent bubbles from accumulating in a bellmouth section outside an epoxy insulator, by completely burying the bellmouth-structure portion of the epoxy insulator in an epoxy insulator. SOLUTION: A cable head is formed by placing a molded epoxy insulator 2 on a center conductor 1 at a point in a porcelain tube 5 where insulating compound 4 is filled, and the epoxy insulator 2 has bellmouth structure on the surface side. Semi-conductive paint 3 is applied to this structural portion in order to use the structural portion for electric field mitigation. A recess formed as the result of the bellmouth structure is completely filled with an epoxy insulator 6. An epoxy insulator 6 formed in advance may be used for filling; however, it is preferable that the epoxy insulator for filling should be formed on the epoxy insulator by molding additional epoxy resin. As a result, it is possible to prevent bubbles from accumulating in the bellmouth section outside the epoxy insulator when insulating compound is injected into between the epoxy insulator and the porcelain tube.
