High-power dye laser in the near infrared

Atmospheric and meteorological Lidar: from pioneers to space applications

“…Then, the search was directed to other metallic species like potassium at 766.4 nm [39], lithium at 670.8 nm [40], calcium at 422.7 nm and ionized calcium at 393.4 nm [41]. As a necessary step prior to any atmospheric measurements, the researchers developed new Nd 3+ :YAG pumped dye lasers [42].…”

Single-frequency pulsed dye laser with injection of lowpower radiation

“…Separation of the functions of the spectrum control and power amplification has been used successfully in systems with multistage amplification. 2 The use of superregenerative amplification has a number of advantages, in particular, it makes it possible to use a master oscillator with a very low output power and to generate high-power single-frequency radiation even when the radiation of the master oscillator is of the multifrequency type. 3 The published results of the experimental investigations 3 " 6 have demonstrated the promise of the injection method in the generation of high-power narrow-band tunable radiation, but these results are far from the best that can be achieved.…”

Applications des lasers à l'étude de l'atmosphère

“…De la même façon et dans le même domaine d'altitude que pour le sodium, grâce à un laser à colorant (DOTC) pompé par un laser à rubis [25], on a pu étudier la concentration et le profil vertical du potassium, dont les concentrations (~ 100 atomes cm-3) sont pourtant inférieures d'un facteur 10 à 50 à celles du sodium. Cette étude simultanée des deux alcalins a ainsi contribué à la solution partielle du problème de leur origine [26] (Fig.…”
