第13講 Lesson 4: Passive Mode Locking

L13_A
        Lesson 4: Passive Mode Locking
        4-1  Master equation
               Temporal effect: SPM effect
               Carrier‐envelope phase (CEP) shift
        4-2  PML with SAM only
               Does “fast” saturable absorber really exist
               Assumptions of Sec. 4‐2
               Fast saturable absorbers
 
 
L13_B
        Lesson 4: Passive Mode Locking
        4-2  PML with SAM only
               Slow gain
               Approximated solution
               How to calculate the constant gain
               Simplified (real) master equation
               Real sech solution
 
L13_C
        Lesson 4: Passive Mode Locking
        4-2  PML with SAM only
               Real sech solution
