RandomArray from user defined distribution?

I'd like to use the RandomArray to produce some data from 
what I think is a Poisson distribution in t
P[t] = a^2 t Exp[-a*t]  where a is mean, sigma.

I see one can use RandomArray to produce sample data from a 
lot of continuous distributions but the Poisson isn't among 
them (it's only available in the discrete form).

I've made a bunch of crippled attempts to force my P[t] to 
put out examples but have failed. Any suggestions? Thanks.
