The simplified rate equation model provides a simple and fast tool for laser designer to develop calculations of pulse energy, peak power and width. A modified rate equations model had been numerically investigated. In order to control and time stabilize the pulse repetition rate, the pulsed pumping was studied. To increase the stability of laser system, an automated pulsed pumping technique had been proposed. Finally, the temperature distribution in the active medium had been studied for continuous and automated pulsed pumping technique Issued also as CD Passively Q- switched Q- switched Solid - state laser Hatem Mahmoud Elghandour , Supervisor Jala Elazab , Supervisor Mohamed Atta khedr , Supervisor http://172.23.153.220/th.pdf Nazla Revisor Samia Cataloger ddc TH 49305 49305 ddc 0 CUCL cl210 2024-02-11 Cai01.24.12.Ph.D.2014.Ha.S 01010110064516000 2023-09-22 00:00:00 TH ddc 0 CUCL cl2u8 2024-02-11 Cai01.24.12.Ph.D.2014.Ha.S 01020110064516000 2023-09-22 00:00:00 64516.CD CD
