TTL input circuit to drive diode

Hi. I need a little help with something that should be pretty basic. I have a control board that has a TTL output to turn on and off a laser. The laser is nothing more than a diode that consumes about 60mA. So, I want to be able to turn the diode on or off with the TTL output. I don't really know much about TTL requirements. But, would a NPN transistor with resistor between the base and the TTL Output work? (Collector to + side of diode, emitter to GND.)? If not, what would be the best thing to do?
Thanks!
Gary
