35.1 W all‐solid‐state 355 nm Ultraviolet Laser
Laser Physics Letters, 2010Co-Authors: Xingpeng Yan, Qiang Liu, Honglei Chen, Ming Gong, Dongsheng WangAbstract:We presented an efficient 35.1 W all-solid-state 355 nm Ultraviolet Laser. The external cavity nonlinear frequency conversion was used while a 100-W level AO Q-switched Nd:YVO4 MOPA Laser was used as the infrared source. Type I noncritical phase-matching LBO and type II phase-matching LBO were used for frequency doubling and sum-frequency mixing respectively. About 100 W TEM00 mode 1064 nm Laser was obtained from the MOPA Laser when the pulse repetition rate increased from 65 kHz to 100 kHz. The highest 35.1 W average power of 355 nm Ultraviolet Laser was obtained from the nonlinear frequency conversion at 70 kHz with the pulse duration of 15.7 ns and optical conversion efficiency of 35.8% (infrared to Ultraviolet), corresponding to the pulse peak power and pulse energy of 32 kW and 0.5 mJ respectively. The average power of Ultraviolet Laser varied from 28.5 W to 34.9 W when the pulse repetition rate decreased from 100 kHz to 65 kHz. The detailed output performance varying with pulse repetition rate, and the power stability of the Ultraviolet Laser, were also investigated.

Extreme-Ultraviolet Laser metrology of O I transitions
Monthly Notices of the Royal Astronomical Society: Letters, 2008Co-Authors: T.i. Ivanov, Edcel J. Salumbides, M.o. Vieitez, P.c. Cacciani, C.a. De Lange, Wim UbachsAbstract:Some 16 transitions in atomic oxygen originating from its 3 P ground state were measured using a tunable narrow-band extreme-Ultraviolet Laser source, with an unprecedented accuracy of �λ/λ = 8 × 10 −8 . The results are relevant for comparisons with spectral absorption features observed in the line of sight of quasars, in order to test a possible variation of the fine-structure constant α on a cosmological time-scale.

EXTREME Ultraviolet-Laser SPECTROSCOPY ON CO IN THE 91-100 NM RANGE
Journal of Chemical Physics, 1992Co-Authors: Pieternel F. Levelt, Wim Ubachs, Wim HogervorstAbstract:Transitions from the ground state X 1Σ+ v=0 to eleven highly‐excited states of CO were investigated using extreme Ultraviolet Laser spectroscopy. Excited states were detected using a two‐photon ionization scheme. Improved values of band origins could be deduced from an absolute calibration of the extreme Ultraviolet Laser radiation against the I2 standard in the visible wavelength region. Accurate predissociation rates followed from linewidth analyses of individual rotational lines.
