Abstract
We present the diode pumping of a Nd-doped strontium and lanthanum (Nd:ASL) crystal Sr<sub>1-x</sub>La<sub>x-y</sub>Nd<sub>y</sub>Mg<sub>x</sub>Al<sub>12-x</sub>O<sub>19</sub> (0.05 ≤ x ≤ 0.5; y = 0.05) for second harmonic generation around 450 nm. In order to fulfill the pumping requirements of this crystal, we have developed a high-brightness pump source based on a tapered amplifier in an extended cavity with a volume Bragg grating for wavelength stabilization. A pump brightness of 110 MW.cm<sup>-2</sup>sr<sup>-1</sup> has been obtained with a linewidth lower than 80 pm at 798 nm. This laser source has been used to pump a Nd:ASL crystal to obtain 300 mW at 906 nm and 53 mW at 453 nm by intracavity doubling with a LBO crystal.
