In this Letter,we realized the phonon-assisted Q-switched laser operation in Yb∶YCOB crystal.Differing from previous laser wavelengths below 1.1 μm,we extended the wavelength to 1130 nm by amplifying multiphonon-assisted electronic transi-tions.At a repetition rate of 0.1 kHz,the laser output power was 82 mW with a pulse width of 466.1 ns,corresponding to a high peak power of 1.76 kW and a single pulse energy of 0.82 mJ,respectively.To the best of our knowledge,this represents the highest pulse energy among all Yb3+-doped crystal lasers at the wavelength beyond 1.1 μm.Such a large pulse energy could be explained by the laser rate-equation theory.These results indicated that the electron-phonon coupling effect not only extends the lasing wavelengths but also enables a fast temporal response to support nanosecond,picosecond,even femto-second pulse laser operation.
