“…These dye lasers can be scanned over their full tuning range by changing the angle of tuning mirror using a picomotor actuator (Newport, model: 8302) with a resolution of 30 pm/step. Such tunable dye lasers are important for the selective-photoionization experiments and laser isotope separation [18,19].…”

Lithium isotopes (6,7Li) are of prime importance for nuclear industry. Especially, highly enriched 6Li is needed in fusion reactors to produce clean energy on large scale. In this paper, we report studies on Li isotope separation by isotope-selective three-color photoionization using ‘kHz’ repetition rate narrowband dye lasers in conjunction with time-of-flight mass spectrometer. The method established yields a high degree of selectivity by tuning the dye lasers to respective 6,7Li resonance levels and demonstrated the enhancement of low abundant (7.5%) 6Li up to 92.86% at signal level. The dependence of photo-ionization yield, isotope selectivity and abundance enhancement on laser powers are also investigated. The proposed photo-ionization scheme [2S1/2 → 2P1/2,3/2 → 2D3/2,5/2 1S0 (Li+)] enables the high photo-ionization yield and large enhancement (>12 fold) in 6Li abundance.

“…There are some experimental studies of the gain competition in two-wavelength dye lasers for both parallel and orthogonal case polarizations but to the best of our knowledge a theoretical model for gain competition has not been presented [2][3][4][5][6][7][8][9].…”

“…In dye lasers pumped by pulsed lasers, the temporal stretching of pump laser pulses increases the energy conversion efficiency and tuning range of the dye laser along with a decrease in its linewidth. The linewidth of the dye laser output depends mainly on the passive linewidth of the resonator and the number of roundtrips taking place in the resonator (Khare et al, 1995). The number of round-trips depends upon the pulse duration of the pump laser.…”
