Output power varies as the square of the DC voltage applied. If +28V gives 50W CW output, then 14V will give 12.5W output for the same drive level. Hopwever, if the DC voltage is greater than approx 32V and a duty cycle of greater than 20% is applied or a pulse width of greater than 100ms is applied, the module will shut down. +50V is the upper limit of DC voltage that can be used. Damage may be casued if you apply greater than +50V DC.
