High-pressure pulsed molecular lasers

Gaussian Modes in High Loss Laser Resonators

“…4 is Loo = 23%, which is small compared to the laser gain of about 5 m 1 . 13 From Eq. (34) the mode discrimination in one amplifier stage is D = (1 + 2 /WM 2 )-= 0.77 so the higher order mode is only weakly damped.…”

Feasibility of oil slick removal from sea water using power lasers

“…However, a further study is required to evaluate the reach and the effects of outward scattering. At the present state of the art, only CO2, CO, and some chemical lasers of the hydrogenhalogen variety are capable of the above indicated efficiency and output (16)(17)(18).…”

Generation of coherent, broadband X-ray and mid-IR pulses in a noble-gas-filled hollow waveguide

“…It should be noted that, at 25 atm, the gain medium loses its modulation and becomes a true continuum across 1.2 THz of bandwidth over the entire vibrational branch. Unfortunately it is technologically impractical to design a large aperture, discharge pumped amplifier which operates at greater than 10 atm of pressure [5].…”
