I would try drinking lots of water, sucking on some hard candy or using cough drops for a week to see if things calm down. If not, I would ask for pulmonary function tests.
Though the chances are slimer, a very mild case of pertussis (whooping cough) could cause coughing fits from laughing. I had pertussis 2 years ago, and laughing was almost impossible. However, I had a severe case and my coughing was unrelenting and violent enough to fracture my ribs in 7 different locations.
TB disease seems very unlikely unless you have at least one of the other symptoms like, night sweats, fevers, feel fatigued and/or cough alot with blood stained sputum.
Best of fortune,
Celeste
