Nd:KGW Laser under Flashlamp-pumping at Repetition Rate up to 50 Hz and Average Power of 70 W (free-lasing and Q-switched mode)

1997

The laser performance of Nd:KGd(WO4)2 crystal or Nd:KGW has been studied under flashlamp-pumping in the free-running and Q-switched mode (with active or passive Q-switching) at repetition rate up to 50 Hz. Maximum output powers respectively of 70 and 30 W were achieved at 1.06 pm with a maximum efficiency of 6%. Free-running emission was also obtained at 1.35 pm with a maximum average power of 24 W and a total efficiency of 2.9% at this wavelength. A comparison with a similar Nd:YAG crystal is given showing a noticeable advantage for Nd:KGW.

Optical rotary power at the resonance of the terbium F-7(6)-> D-5(4) line in terbium gallium garnet

1998

0038-1101; The Tb3+ absorption line F-7(6)-->D-5(4) Of the Terbium Gallium Garnet crystal is excited with an Argon ion laser. The Verdet's constant has been determined and reported against 1/lambda(2), showing no significant resonant behaviour at absorption resonance. The utility and the constraints of the crystal at this particular resonant wavelength are pointed out. (C) 1998 Elsevier Science Ltd. All rights reserved.

High-Resolution Nonlinear Raman-Spectroscopy in Gases

1990

0377-0486; The resolution in the Raman spectra of gases has been greatly improved by the development of the different methods of non-linear Raman scattering. When two laser beams, one of which has a tunable frequency, are focused in a sample, a stimulated Raman process occurs as soon as the frequency difference between the two lasers is equal to a Raman-active rovibrational or rotational transition frequency. The Raman resonance can be detected in different ways: by coherent anti-Stokes Raman scattering (CARS) or the corresponding Stokes process (CSRS), by a gain in one of the beams (stimulated Raman gain spectroscopy, SRGS) or a loss in the other (inverse Raman spectroscopy, IRS), or even …
