I think you just connected a differential output to a laser that wanted a single ended input. It might have damaged the laser's modulation input.
If you can verify that the output voltages are equal and opposite in polarity at all times (use a voltmeter), you'll need to get the laser mod imput repaired, or get enough detailed advice to allow you to fix it yourself.
