Definition 1:
Haha - used to express laughter anywhere you can't say it, for example IM, instant messaging or via email.

The minor difference between haha and hehe is that haha is often used when laughing at someone, while hehe is used while laughing with someone. It might be unconcious to most people, but it's true.

Definition 2:
Ha-ha - when haha is pronounced like 'Ha-ha', it often expresses that one do not find something humourous; ironic.

I also found some pretty random ancronyms for haha online:

Having A Heart Attack
Houston Area Hound Association (Texas)
Human-Anti-Humanized Antibodies (immunogenicity testing assay)
Example 1 (haha): You don't know who Shakespeare was? Haha!
Example 2 (ha-ha): Ha-ha, how funny!
Example 3 (hehe): Hehe, you're so funny!
