Title: Method of controlling wavelength of laser
Inventor: WAKABAYASHI OSAMU
IPC: H01S3/134
Filed: 1988-03-31
Abstract: PURPOSE:To quickly detect an end of an overlap control operation by a method wherein a transmitted wavelength of a prescribed wavelength selection element out of wavelength selection elements is shifted by a definite amount and the center wavelength power before this shift is compared with the center wavelength power after this shift. CONSTITUTION:A CPU 302 controls a wavelength selection characteristic (transmitted center wavelength and selected center wavelength) of etalons 101, 102 via drivers 303, 304; it executes an overlap control operation in such a way that a center wavelength of a sample beam, i.e. an output beam of an excimer laser, coincides with a previously set and desired wavelength (center wavelength control operation) and that the center wavelength power becomes a maximum. That is to say, when an etalon #E1 and an etalon xsiE2 are overlapped defectively, an overlap subroutine is executed; a transmitted wavelength of the etalon #E2 whose free spectral range is large is shifted one after another by a prescribed shift amount in the direction of an arrow. When the transmitted wavelength of the etalon #E2 is shifted in the direction opposite to the previous direction, it is judged that the overlap operation is finished. By this setup, an end of the control operation can be detected quickly.

Filed: 1989-03-30
Abstract: PURPOSE:To attain the coexistence of the elimination effect of a noise and the fast switching of a current by separating a capacitor for bypassing from a load circuit when the current on the load circuit changes, and connecting the capacitor again to the load circuit after making the terminal voltage of the capacitor follow the terminal voltage of the load circuit. CONSTITUTION:Charge (or discharge) on the capacitor C with the voltage same as the terminal voltage Vr of a coil L is performed by a charge/discharge circuit 11 during a time T when a switch S is connected to a charge/discharge circuit 11 side. Such charge-discharge is performed at high speed since the output resistance of the charge/discharge circuit 11 is very low. The terminal voltage Vc of the capacitor C before the switch S is connected to a coil L side and the terminal voltage Vr of the coil L are changed to rise from V3 to V4, and even when the switch S is connected to the coil L side at such state, no charge/discharge on the capacitor C is performed since the terminal voltage of the capacitor C is equal to that of the coil L, therefore, no transient phenomena occurs. In such a way, it is possible to vary an oscillation frequency at high speed for the change of a control voltage Vt.
