Thank you Xena, for the comment!
Yes, my driver (LDP-V 240-100, manual attached here) is capable of providing up to 240 A pulses.
Its super counterintuitive that the driver only takes in a low electrical power (19 mW) to deliver such a high pulse power (65 W). So if I am understanding it right, I still need a peak current of 20 Amps (at 9.5 V) to drive my diode but the average current drawn from my power supply will be close to 2 mA (20 A x Duty cycle)?
