The laser I opted for was the Cynosure Cynergy, which is a newish (2006) PDL/YAG combo. It hits the vein with PDL followed immediately by a low powered YAG. The combo works because the PDL does something sciencey in the first hit which makes the target veins more susceptible to the YAG hit afterwards. Also, the YAG is used at 2-3 times lower power than normal (which reduces redness and swelling).
I believe the first hit with the PDL somehow deoxygenates the blood and thus makes it a better target for the YAG.
"The sub-purpuric, pulse-dye laser converts oxy-hemoglobin to methemoglobin and micro-clots-increasing absorption of the Nd:YAG wavelength by 300 to 500 percent and thereby enabling reduced Nd:YAG fluence for enhanced client safety. In addition, since greater penetration depth is achieved, outcome results are optimized."
