No. Laser light is highly coherent, meaning the phase of the wave packets in the beam maintain a fairly constant value over short periods of time. Sunlight is highly incoherent meaning the phase relationship between the wave packets is randomly changing.

You can think of a laser of consisting of a bunch of little hammers that strike an object at the same time giving it an impulse. Sunlight is like a bunch of tiny hammers landing at random times resulting in no 

A new kind of efficient, solar-powered laser has been developed by researchers at the Tokyo Institute of Technology, in Japan. They hope to use the laser to help them realize their goal of developing a magnesium combustion engine. The researchers described the new laser in a recent issue of Applied Physics Letters.
