Excited-state absorption in the range of pumping and laser efficiency of Cr4+:forsterite.
The absorption saturation and the laser efficiency of Cr(4+): forsterite were measured with 1064-nm (E || b), 980-nm (E || c), and 780-nm (E || b) pulsed laser pumping. A slope efficiency of 32% was obtained for the 980-nm (E || c) pump wavelength, where the excited-state absorption losses were shown to be negligible.
