Question: How to get a simpler expression of the Laplace transform

I'm presently checking the ability of inttrans:-laplace to give results one can find in the literature.
Unfortunately the inttrans:-laplace's  answers are sometimes more complex than those published in the literature and I'm not capable to simplify the output.

For instance

f := (t+1)/sqrt(t^2+2*t);
L := laplace((t+1)/sqrt(t^2+2*t), t, p);

expresses L in terms of WhittakerW and BesselK(0, p) functions as the answer simply is

exp(p)*BesselK(1, p)

How can I get this result with Maple?
