  The High Rep­e­ti­tion-Rate Ad­vanced Petawatt Laser Sys­tem (HAPLS) forms part of the Eu­ro­pean Union's Ex­treme Light In­fra­struc­ture Beam­lines pro­ject (ELI-Beam­lines) which will be the first in­ter­na­tional laser re­search in­fra­struc­ture of its kind. HAPLS will gen­er­ate peak pow­ers greater than one petawatt at a rep­e­ti­tion rate of 10 Hz with 30fs wide pulses. ELI will en­able un­prece­dented tech­niques for many di­verse areas of re­search. HAPLS re­quires a high-pre­ci­sion tim­ing sys­tem that op­er­ates ei­ther in­de­pen­dently or syn­chro­nized with ELI's sys­tem. Green­field Tech­nol­ogy, a pro­ducer of ma­ture pi­cosec­ond tim­ing sys­tems for sev­eral years, has been hired by LLNL* to pro­vide just such a tim­ing sys­tem. It con­sists of a cen­tral Mas­ter Tim­ing Gen­er­a­tor (MTG) that gen­er­ates and trans­mits se­r­ial data streams over an op­ti­cal net­work that syn­chro­nizes local multi-chan­nel delay gen­er­a­tors which gen­er­ate trig­ger pulses to a res­o­lu­tion of 1ps. The MTG is phase-locked to an ex­ter­nal 80 MHz ref­er­ence that en­sures a jit­ter of less than 10ps. The var­i­ous qual­i­ties and func­tions of this tim­ing sys­tem are pre­sented in­clud­ing the Lab­VIEW in­ter­face and pre­ci­sion phase lock­ing to the 80MHz ref­er­ence.
