Abstract

ÖZET GAS LASER KAVÎTESİNÎN, FABRY-PEROT 1NTERFEROMETRES1 REFERANS OLARAK KULLANILARAK, STABÎLİZASYONU VE PÎEZO ELEKTRİK MALZEMESİNİN (PZT-4) KARAKTERİSTİ?İNİN ARAŞTIRILMASI İbrahim, BASSAM Yüksek Lisans Tezi, Fizik Bölümü Tez Yöneticisi : Doç. Dr. Ramazan AYDIN Eylül 1987, 54 Sahife Laser spectroskopisi ve uygulalamalarmda kullanıl mak amacıyla bir gas laser kavitesinin stabilizasyonu incelendi. Bu çalışmada Michelson interferometresi, elektronik kontrol sistemi ve piezo-elektrik malzemeler yardımıyla stabil bir kavite elde edildi. Ayrıca laboratuar da gerçekleştirilen uygun bir kontrol sistemi kullanılarak PZT-4 piezo malzemesinin mekanik ve elektriksel karakteris tikleri araştırıldı. - iv -

ABSTRACT STABILIZATION OF A GAS LASER CAVITY BY MEANS OF FABRY-PEROT INTERFEROMETER AND AN INVESTIGATION OF THE CHARACTERISTICS OF THE PIEZOELECTRIC MATERIAL (PZT-4) Ibrahim, BASSAM M.S. in Physics Department Supervisor: Assoc. Prof. Dr. Ramazan AYDIN September 1987, 54 pages Stabilization of a gas laser cavity has been studied for laser spectroscopy and used for high-resolution applications. In this work a stable cavity has been achieved using Michelson interferometer, electronic control system and piezoelectric materials. Furthermore, the characteristics of the piezo-element (PZT-4) have been investigated by means of a suitable control system which has been designed and constructed in our laboratory. - iii -
