We　report　a　high-power　chirped　pulse　amplification　(CPA)　based　on　nonlinear　amplifying　loop　mirror　(NALM)　oscillator　and　Yb-doped　rod-type　photonic　crystal　fiber　(PCF).　An　all-polarization-maintaining　NALM　mode-locked　fiber　oscillator　was　used　providing　an　average　power　of　9.4　mW,　a　pulse　duration　of　5.3　ps　at　the　repetition　rate　of　21　MHz.　After　pulse　stretching,　selection　and　amplification,　an　average　power　of　120　W　with　the　pulse　duration　of　145　ps　at　repetition　rate　of　4.2　MHz　has　been　achieved.　The　pulse　duration　is　compressed　to　14　ps　using　a　pair　of　reflective　gratings　coated　by　gold　film.　In　order　to　prevent　the　damage　of　the　gratings,　the　compressed　average　power　is　limited　to　51　W.　The　compressed　pulse　average　power　can　be　further　improved　by　using　transmissive　gratings　coated　by　dielectric　film.
