Can anybody answer these questions (or any of them)?
1. Is the beam quality of DPSS lasers better than that of single diode lasers? If so, why?
2. Why did Nichia bother to invent the 405nm diode? Why not just frequency double the output from an 808 LD?
3. What is the size of the laser light emitting area in a laser LD? How does this compare to the laser light emitting area in the lasing crystal of a DPSS?
Just wondering....
