Vanadium-pumped titanium x-ray laser.
A new laboratory x-ray laser is described that is resonantly photopumped by two 3d ? 2p emission lines in fluorinelike vanadium (Z = 23) and lases on several 3p ? 3s transitions in neonlike titanium (Z = 22). Calculations show that five of the laser lines have gains greater than 5 cm(-1) for reasonable values of the pump lines, with the shortest wavelength of the five being at 32.65 nm.
