“…19 These effects are minimized by use of appropriate dye solvent recipes at a temperature where the thermal dispersion is minimal. 5,20 The recipe that we use is 2.0 g of Rhodamine 590 tetrafluoroborate dissolved in a solution comprising 1.0 L of methanol, 3.6 L of Ammonyx, and 4.4 L of distilled water. The best performance is achieved when the dye solution is cooled to 5Ϯ3°C.…”

Turn-on transient dynamics in a multimode, compound-cavity laser

et al. 1997

The turn-on-time statistics for an individual longitudinal mode and the total intensity of a multimode laser are shown to be very different. In both experiment and theory we find that the differences are due mainly to transitory modes that decay as a result of frequency-dependent losses and gains. Associated with this phenomenon is a kink in the time evolution of the mode intensity, but not in the total intensity, that represents a transition in the dynamics from domination by independent growth of all modes to domination by competition between modes with different net gains. This unequal competition increases the average and the standard deviation of the individual mode turn-on time. The experimental dye-laser system has a thin gain medium (100 m) that is strongly coupled to a short cavity (2.5 cm) and is adjacent to one of the cavity mirrors. The opposite cavity mirror serves as a relatively weak output coupler. The presence of the thin gain medium in the cavity causes the effective pump and loss rates to be frequency dependent. The result is a transient spectrum in which the cavity modes that have the highest net gain dominate the system more as the turn-on transient progresses. The gain spectrum is found to be strongly affected by the frequency dependence of the compound-cavity modes. Using realistic laser parameters, numerical simulations of a multimode laser model ͕developed in companion paper [J. Opt. Soc. Am. B 14, 191 (1997)]͖ yield turn-on dynamics and statistics that agree well with those measured experimentally.

“…The argon ion laser wavelength is selected with a prism U L =488 and 514 nm). The dyes rhodamine 110 in ethylene glycol [21] (wavelength range 550-570 nm) and rhodamine 6G in ethylene glycol (A L =580-620 nm) are applied. The dye laser wavelength is tuned with a single-plate quartz birefringence filter (thickness0.5 mm).…”

The accumulation of molecules in the P-isomer ground state of DODCI in ethylene glycol is studied experimentally and theoretically. The P-isomer S 0 state is populated by S 0 -S, absorption of cw argon ion laser light or dye laser light at various wavelengths. The population is probed by the absorption of a weak He-Ne laser. The recovery to the thermal ground-state equilibrium of N and P isomers is determined by measuring the temporal probe light absorption after pump laser switch-off. A steady-state level population theory is derived and applied to determine P-isomer SQ-S, absorption cross sections and transfer efficiencies between N isomers and P isomers.

“…The wavelength of the lithium D-line resonances (670.8 nm in air) currently restricts the choice of light sources to two different kinds of lasers: dye lasers and external cavity diode lasers (ECDLs). Dye lasers typically deliver watt-level output of monochromatic light in a diffraction limited beam [2]. The drawbacks of this technology are an important maintenance effort, high intrinsic phase noise, and the requirement of an expensive pump laser.…”

An all-solid-state laser source at 671 nm for cold-atom experiments with lithium

et al. 2011

We present an all solid-state narrow linewidth laser source emitting 670 mW output power at 671 nm delivered in a diffraction-limited beam. The source is based on a frequency-doubled diode-endpumped ring laser operating on the 4 F 3/2 → 4 I 13/2 transition in Nd:YVO 4 . By using periodically-poled potassium titanyl phosphate (ppKTP) in an external buildup cavity, doubling efficiencies of up to 86% are obtained. Tunability of the source over 100 GHz is accomplished. We demonstrate the suitability of this robust frequency-stabilized light source for laser cooling of lithium atoms. Finally a simplified design based on intra-cavity doubling is described and first results are presented.
