“…12 The frequency shift arising in the multipass amplification in the Ti:Sa crystals ͑Ͻ10 MHz͒ was determined by monitoring the interference between the pulse-amplified laser beam with the cw NIR output of the ring laser 13 and taking the Fourier transform of the beat-note signal recorded when the 396 nm laser was on resonance with the EF to Rydberg transitions.…”

The transition wave numbers from selected rovibrational levels of the EF 1 ⌺ g + ͑v =0͒ state to selected np Rydberg states of ortho-and para-D 2 located below the adiabatic ionization threshold have been measured at a precision better than 10 −3 cm −1 . Adding these wave numbers to the previously determined transition wave numbers from the X 1 ⌺ g + ͑v =0, N =0,1͒ states to thestates of D 2 and to the binding energies of the Rydberg states calculated by multichannel quantum defect theory, the ionization energies of ortho-and para-D 2 are determined to be 124 745.394 07͑58͒ cm −1 and 124 715.003 77͑75͒ cm −1 , respectively. After re-evaluation of the dissociation energy of D 2 + and using the known ionization energy of D, the dissociation energy of D 2 is determined to be 36 748.362 86͑68͒ cm −1 . This result is more precise than previous experimental results by more than one order of magnitude and is in excellent agreement with the most recent theoretical value 36 748.3633͑9͒ cm −1 ͓K. Piszczatowski, G. Łach, M. Przybytek et al., J. Chem. Theory Comput. 5, 3039 ͑2009͔͒. The ortho-para separation of D 2 , i.e., the energy difference between the N = 0 and N = 1 rotational levels of the X 1 ⌺ g + ͑v =0͒ ground state, has been determined to be 59.781 30͑95͒ cm −1 .

The transition wave number from the EF 1 ⌺ g + ͑v =0,N =1͒ energy level of ortho-H 2 to the 54p1 1 ͑0͒ Rydberg state below the X + 2 ⌺ g + ͑v + =0,N + =1͒ ground state of ortho-H 2 + has been measured to be 25 209.997 56Ϯ ͑0.000 22͒ statistical Ϯ ͑0.000 07͒ systematic cm −1 . Combining this result with previous experimental and theoretical results for other energy level intervals, the ionization and dissociation energies of the hydrogen molecule have been determined to be 124 417.491 13͑37͒ and 36 118.069 62͑37͒ cm −1 , respectively, which represents a precision improvement over previous experimental and theoretical results by more than one order of magnitude. The new value of the ionization energy can be regarded as the most precise and accurate experimental result of this quantity, whereas the dissociation energy is a hybrid experimental-theoretical determination.

“…They preprogrammed pulse envelopes, in the range of durations between 10 ns and 1 s, by acoustooptical modulator ͑AOM͒ intensity modulating the output of a cw Ti:sapphire laser and subsequently amplifying these in a series of multipass amplifiers; this led to XUV pulses at bandwidths as low as 55 MHz. 10 Dupré and Miller extended the development of injection-seeded pulsed Ti:sapphire lasers, focusing on methods to optimize cavity stabilization, to achieve pulse energies of 100 mJ at bandwidths as low as [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] MHz ͓full width at half maximum ͑FWHM͔͒ for use in high-resolution spectroscopy. 11 When using injection-seeded pulsed laser systems in high-resolution spectroscopic applications, either at the fundamental wavelength or at generated harmonics, effects of time-dependent gain in the amplifier will give rise to phase excursions deviating from the carrier wave.…”

“…Chu and co-workers 13,14 addressed the chirp issues of dye amplifiers and their consequences for precise frequency calibration in relation to the spectroscopy of positronium. Eyler and co-workers 15,16 thereupon investigated the phase dynamics of dye amplifiers in further detail, while Reinhard et al 17 and Eikema et al 18 developed methods to compensate for chirp effects by manipulating the phase of the seed light via an electro-optic modulator before amplification.…”

A narrow-band tunable injection-seeded pulsed titanium:sapphire laser system has been developed for application in high-resolution spectroscopic studies at the fundamental wavelengths in the near infrared as well as in the ultraviolet, deep ultraviolet, and extreme ultraviolet after upconversion. Special focus is on the quantitative assessment of the frequency characteristics of the oscillator-amplifier system on a pulse-to-pulse basis. Frequency offsets between continuous-wave seed light and the pulsed output are measured as well as linear chirps attributed mainly to mode pulling effects in the oscillator cavity. Operational conditions of the laser are found in which these offset and chirp effects are minimal. Absolute frequency calibration at the megahertz level of accuracy is demonstrated on various atomic and molecular resonance lines.
