Inventor: AKIBA HIDEO
IPC: C23C14/34
Filed: 2003-12-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and device for laser irradiation after forming optical thin film which is capable of forming a fluoride optical element having improved interfacial absorption by effectively utilizing laser of a small beam diameter and irradiating the whole lens surface of a large area with the laser by the use of a relatively simple and inexpensive optical system.  <P>SOLUTION: In the laser irradiation, a fluoride optical element is manufactured on base material and, thereafter, the fluoride optical element is reformed into a low absorptive fluoride optical element through the laser irradiation. Therein, upon the laser irradiation to the base material of large area, beam shape is split and faired such that the laser beam has a distribution of at least the length of a half or more of outer diameter of the base material, the base material is irradiated with the split laser beam, thereby, the laser of smaller beam diameter is effectively utilized and the fluoride optical element having an improved interfacial absorption can be formed.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To secure stable power feed for the fluctuation of the impedance value of a sample by sputtering generated during analysis.  <P>SOLUTION: A generator 12 of a glow discharge emission analyzer detects a power value Pf of high-frequency power Wf applied to a sample and a reflection power value Pr of reflection power Wr returning from a sample by a power measurement section 12b, and transmits the result to a control section 12c. The control section 12c computes the difference between the power value Pf and the reflection power value Pr, and determines whether the computed result is equal to a reference value. If the computed result is not equal to the reference value, an instruction for changing the power value Pf so that the computed value is equal to the reference value is outputted to the high-frequency power Wf.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
