112 Design and Construction of 10 W Average Power Ultra short Pulse Fiber Laser at 1060 nm Wavelength Using 1550 nm Fiber Laser Seed M J Hekmat m hekmat@ec iut ac ir January 2019 Department of Electrical and Computer engineering Isfahan University of Technology Isfahan 8415683111 IranFirst supervisor Dr Masood Omoomi omoomi@cc iut ac irSecond supervisor Dr Asghar Gholami gholami@cc iut ac irAdvisor Dr Abolghasem Zeidaabadi NezhadDepartment graduate program coordinator Dr GholamReza YousefiAbstract In this research by adopting an alternative novel approach to ultra short giant pulse generation whichbasically originated from difficulties with traditional employed methods an optimized Er Yb co doped double cladfiber amplifier is applied to boost output average power of single mode output pulses to a high level of 2 W at 1 59 m central wavelength Output pulses of approximately 63 fs pulse width at 52 MHz repetition rate are obtained in anall fiber monolithic laser configuration The idea of employing parabolic pulse amplification for stretching outputpulses together with high power pulse amplification using Er Yb co doped active fibers for compressing and boostingoutput average power play crucial roles in obtaining desired results The proposed configuration enjoys massiveadvantages over previously reported literature which make it well suited for high power precision applications such asmedical surgery Detailed dynamics of pulse stretching and compressing in active fibers with different GVD parametersare numerically and experimentally investigated We also report the design and performance of a high powerfemtosecond laser source near 1 m wavelength which is generated from an octave spanning supercontinuum SC pumped by an Er doped mode locked laser The laser system delivers 5W average power at 52MHzrepetition rate and 135 fs pulse duration Index Terms Er Yb fiber amplifier SESAM Mode locking Ultra short pulses
