We describe and compare three methods we have used to stabilize the frequency of an end-pumped, tunable La{sub 0.85}Nd{sub 0.15}MgAl{sub 11}O{sub 19} (LNA) laser to the absorption lines of {sup 4}He or {sup 3}He near 1083 nm. The first two methods vary the thickness of an intracavity etalon which is used for tuning and narrow banding of the laser output. The third method varies the length of the laser cavity. All three methods yield satisfactory stabilization of the laser frequency although controlling the tilt angle of a solid etalon is the simplest and most reliable method.
