摘　　要：We report on a polarization-adjustable picosecond deep-ultraviolet (DUV) laser at 177.3 nm.The DUV laser was produced by second harmonic generation from a mode-locked laser at 355 nm in nonlinear optical crystal KBBF.The laser delivered a maximum average output power of 1.1 m W at 177.3 nm.The polarization of the 177.3nm beam was adjusted with linear and circular polarization by means of λ/4 and λ/2 wave plates.To the best of our knowledge,the laser has been employed as the circularly polarized and linearly polarized DUV light source for a spin- and angle-resolved photoemission spectroscopy with high resolution for the first time.
