Simple dye laser repetitively pumped by a xenon ion laser

A rhodamine 6G laser and a cresyl violet laser emit light pulses of 0.3-μs pulse length and 10-20 W peak power at a rate of 120 Hz when pumped with an inexpensive xenon ion laser.

A xenon ion pumped blue dye laser

A pulsed xenon ion laser with an output power of 5 kW at 364.5 nm has been used as a pump source for several blue dyes. Broad-band conversion efficiencies exceed 20 percent. The use of a birefringent filter provides tunable output in the blue region of the spectrum with a bandwidth of 0.08 nm and a pulsewidth of 120 ns.     

High-pressure infrared xenon laser with X-ray preionization

The first experimental results are presented of an X-ray preionized argon-buffered xenon laser. The X-rays are generated by a simple electron-beam device located below the 23-cm inner diameter laser chamber. The advantages of X-ray preionization for high-pressure discharge-pumped lasers include the long X-ray penetration depth, high preionization density, and spatial uniformity. The combination of X-ray preionization and techniques to eliminate surface flashover allows energetic operation in 4 atm of argon buffer for the first time in a photopreionized discharge laser. The argon-xenon mixtures lased primarily at 1.73 μm and 2.63 μm with a peak energy of 340 mJ at 4 atm, and a specific energy output of 0.85 J/liter     

Comments on the identification of some xenon ion laser lines

Earlier measurements and level assignments made by the authors for some xenon ion laser lines are reevaluated in light of recent work by Gallardo and coworkers. The lines affected are the 5260.17-, 5260.43-, 4305.75-, and 3759.94-Å lines in xenon and 4647.40- and 4650.22-Å lines attributed to carbon.     

A xenon ion pumped open dye stream laser

A pulsed xenon ion laser with an output power of 1 kW over the blue-green lines was used to pump an open dye stream laser. An efficiency of the order of 40 percent was determined in broad-band mode operation. The bandwidth in this case was 48 nm (from 582 to 630 nm).     

Some observations on multiply ionized xenon laser lines

The intensity profile of the laser lines in pulsed xenon discharges is related to the Xe(IV) emission from the plasma "pinch." The period of the observed intensity modulation of the xenon-laser pulse corresponds to the time for double traversal of the cavity. Evidence is reported for local saturation of two Ar(II) laser lines in pulsed argon discharges.     

High-pressure xenon laser at 1730 Å

Experimental measurements are reported of optical gain due to stimulated transitions between the lowest-bound diatomic states of xenon (Xe) and the repulsive ground state. The optical gain was greatest at a wavelength of (1730 ± 10) Å, where the effective gain cross section is estimated to be7 times 10^{19}cm².     

CW operation of high ionization states in a xenon laser

Continuous laser operation has been obtained on five unclassified lines in ionized xenon. The behavior of these lines with discharge parameters and the lack of correlation with known Xe III lines using the method of laser-induced perturbation spectroscopy suggests strongly these lines originate from Xe IV.     

Enhancement of CO laser efficiency by addition of xenon

The influence of xenon on the performance of a CO laser has been studied. The addition of xenon produced an increase in the conversion efficiency up to 40 percent and a change in the spectral intensity distribution of the laser output.     

New infrared laser lines in argon, krypton, and xenon

Fourteen new infrared laser transitions in Ar, Kr, and Xe ranging from3.725 to 17.233 mum are reported. All of the Kr laser transitions and all but one of the Ar and Xe transitions have upper levels in thesordstate: the majority of the transitions satisfy the conditionDelta K = Delta J. Identification of a previously observed, unidentified laser line at 5.804 μm in Ar is given.     

Investigation of the operating characteristics of the 3.5 µ xenon laser

Amplification at 3.508 μ in pure xenon dc-excited discharges has been measured over a wide range of gas pressures and for several discharge diameters. For pressures greater than 10 mTorr, the unsaturated gain increases monotonically as the pressure decreases. Gain varies inversely as the radius for large bore (radius ≥ 3.5 mm) amplifers, but a complicated, pressure-dependent variation between gain and discharge diameter was observed in amplifiers of less than 3-mm diameter. Gain saturation occurs at low Signal levels and results in small output powers from conventional xenon lasers.
