The excited-state nuclear Zeeman effect and quadratic-electronic Zeeman effect were studied in Pr(3+):LaF(3) using laser-induced hole burning. Hole burning in an external magnetic field gave values for the excited-state enhanced nuclear g tensor of g(x)beta/h = 2.2, g(y)beta/h = 1.9, and g(z)beta/h = 3.6 kHz/G. By applying the field after hole burning, quadratic-electronic Zeeman coefficients as small as 0.1 Hz/G(2) were measured. The hyperfine coupling constant in the excited (1)D(2) level was found to be A(J) = 600 MHz.
