Directly diode-laser-pumped Ti:sapphire laser

Opt Lett. 2009 Nov 1;34(21):3334-6. doi: 10.1364/OL.34.003334.

Abstract

A directly diode-laser-pumped Ti:Al(2)O(3) laser is demonstrated. Using a 1 W, 452 nm GaN diode laser, 19 mW of cw output power is achieved in a potentially portable format. Pumping at this short wavelength induces a loss at the laser wavelength that is not seen for the more typical green pump wavelengths. This effect is characterized and discussed.
