Amplifier cell. This three stage dye laser is available either as an amplifier and frequence conversion unit (FCU), or two amplifiers. Twenty-three patients with this condition, involving the lower limbs and in extensive cases the upper limbs and trunk, have been treated with the flash lamp pulsed tunable dye laser (SPTL-1b, Candela Laser Corp.). The dye laser was tunable over a range of 35 nm with a maximum at lambda = 590 nm for a given dye concentration. Half Butterfly Gain Chips. The dye concentration is then adjusted as the dye laser is operating by adding more solvent or more concentrated dye solution (as appropriate) to the dye solution circulating within tunable laser 11. The molecules of an organic dye laser have a singlet ( S0, S1, and S2) and triplet ( T1 and T2 ) Electron states. Tunability has added an important dimension to a variety of laser devices and led to new systems and applications.

In the following description, which ignores triplet states, it is necesary to remember that energy differences are related to frequency differences via Planck's energy equation. The instant invention relates to a small line width tunable laser, especially a small line width tunable dye laser, comprising the features of the precharacterizing part of claim 1. Achieving Population Inversion. Tunable Ti:Sapphire Laser for Multiphoton Imaging. The first high-performance tunable dye laser was the telescopic design introduced by Hänsch , in 1972. The most useful feature of dye Lasers is their tunability,means the lasing wavelength can be varied over a wide range. Dye cells are "plug & play" and nonlinear crystals are controlled via integrated look-up tables for quick and easy scans. There are also dye lasers that utilize a large volume of dye solution pumped with a flash lamp or a Q-switched laser. Stimulated two-photon absorption spectroscopy and measurements of the Lamb shift in atomic hydrogen are discussed. A miniature tunable dye laser comprises a pair of mirrors opposed along an optical axis and shaped to provide an optical cavity with stable resonance in at least one mode and having a cavity length of at most 50 μm. A pulsed tunable dye laser with a bandwidth of less than 0.004 Å, repetitively pumped by a nitrogen laser, is described. Demonstration of the wide tuning capability of the dye laser from green to yellow to red. RPMC Lasers Confirmation of the diagnosis by a punch biopsy of the lesion was followed by 3 treatments on separate occasions 6 weeks apart with the long-pulsed tunable dye laser. MEMS-VCSEL Swept Sources. Chatrath and Rohrer (2002) used long-pulsed tunable dye laser for the treatment of GF to target the vessels and minimize scarring. Tunable laser systems. Applications of these devices to atomic saturated absorption spectroscopy, the measurement of the fine structure of atomic hydrogen, and the Rydberg constant are explained. A laser dye is inside the optical cavity. Laser Physics IILaser Physics II PH482/582-TS (Mirov) Tunable Lasers Dye lasersTunable Lasers. Such dye lasers can generate pulses with many millijoules. The tunable single frequency lasers, such as dye, solid state (Titan-Sapphire, Nd:YVO4) and hybrid lasers are used worldwide in scientific fields such as atomic cooling, spectroscopy, nanotechnology, etc. Tunable dye laser amplifier chain for laser isotope separation 449 Figure 4.
