Cw X-ray Preionized Pulsed Gas Lasers

We have successfully demonstrated that the cw x-ray generator can work as a preionization source for a pulsed H F laser. The preionization effect of cw x radiation was revealed by a comparative study of with and without applying x-ray photons to the H F laser. Since dose rate of the cw x-ray generator is easily controllable, the laser output could be measured as a function of initial electron n...

Cw Optical Resonance Transfer Lasers (ortl)

Wavelength-agile, single and multiline laser radiation has been obtained from a subsonic gas flow system which is optically pumped with a multiline chemical laser. This optical resonance transfer laser (ORTL) concept was first demonstrated on the 10.6pm DF/C02 system in 1976, Since then, several IR laser pumped molecular lasers have been demonstrated. The pump laser is either a cw HF or DF chem...

Predicaments in CW operation of silicon Raman lasers and amplifiers

We examine limitations of carrier removal with a p-n junction in Raman devices, namely, ineffectiveness at high optical intensities due to the applied field being screened, electrical heat dissipation, and the possibility of thermal instability. © 2006 Optical Society of America OCIS codes: (130.3120) Integrated optics devices, (190.4390) Nonlinear optics, integrated

Modeling of quasi-three-level lasers and operation of cw Yb:YAG lasers.

We present modeling studies of quasi-three-level laser oscillators, the validity of which was revealed by Ti:Al(2)O(3)-pumped Yb:YAG laser experiments, and these results are shown to be in excellent agreement with the theory. As much as 75% slope efficiency was obtained with a hemispherical laser cavity. Previous modeling calculations of laser performance have been valid only for certain specia...
