Generation of 1064 nm pulses accurately synchronized with broadband 794 nm pulses by CW-seeded intracavity non-collinear OPA.
A straightforward all-optical way is demonstrated to synchronize broadband pulses of Ti:sapphire lasers with pulses at 1064 nm, wherein background-free pulses around 1064 nm are generated by non-collinear optical parametric amplification seeded with an intracavity continuous-wave He-Ne laser. The intracavity He-Ne laser provides sufficient seed power to dominate over parametric fluorescence. With an intracavity power of 200 mW, the idler pulse at 1064 nm has the pulse-energy about 6 nJ.
