Is the Ruby Laser the most effective laser treatment to remove my tattoo? (photo)

Hi, [Had to shorten question a lot] I found a very professional looking clinic in my home town. (Cambridge. UK) Today, I was expecting to be zapped with a ND:YAG laser at 1064, but they used a "Q Switched yellow rod Ruby laser". Could someone please reassure me that using the Ruby laser was ok. They had an ND:YAG laser there too, but I was assured that I'd see better results with the ruby one. I did look at Picosure, but the nearest clinic is 3 hours drive and they charge 5 times as much!!
