Gas Laser Chamber Electrode Support for Uniform Primary Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas laser apparatuses face challenges in maintaining uniform primary discharge across the discharge electrodes, leading to non-uniform wear of the first discharge electrode and a reduced service life of the chamber apparatus.
Innovation Solution
The chamber apparatus is designed with a support member made of an insulator, which prevents electrical continuity between the second discharge electrode and the chamber body, thereby enhancing the longitudinal uniformity of the return current and improving the uniformity of the primary discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the second discharge electrode is electrically connected to the chamber body via a conductive support member, then the structural support is simplified, but the uniformity of primary discharge deteriorates and the service life of the chamber apparatus decreases
Solution Approach 1:
The patent introduces an insulating support member as an intermediary between the second discharge electrode and the chamber body. This insulating member prevents direct electrical contact while providing mechanical support, thereby maintaining discharge uniformity and extending service life without complicating the structural support system.
2Manufacturing precision
If a line narrowing module is added to the laser resonator to narrow the spectral linewidth, then the chromatic aberrations are reduced, but the device complexity increases
Solution Approach 1:
The patent introduces an insulating support member as an intermediary between the second discharge electrode and the chamber body. This insulating member prevents direct electrical contact while providing mechanical support, thereby maintaining discharge uniformity and extending service life without complicating the structural support system.

This configuration enhances the uniformity of the primary discharge, reduces non-uniform wear of the discharge electrodes, and extends the service life of the chamber apparatus.
Implementation Method 1
a support member fixed to the chamber body and supporting the second discharge electrode, the second discharge electrode and the chamber body being not electrically continuous with each other via the support member
Implementation Method 2
a first discharge electrode disposed in an internal space of the chamber body and having a longitudinal direction aligned with an optical axis of the laser light; a second discharge electrode so disposed in the internal space that the second discharge electrode faces the first discharge electrode
