I was not aware that this was a heated aspect of this article. I agree that the article lacks the details that would allow an interested scientist to pursue it further. It is important to me because I have. I used a CVD diamond to Raman shift my lab built vanadate laser. I did not follow this with one of my videos because although it worked, the power output was disappointing. The reason is that you need to design the entire laser around this down shifted wavelength and you need to add a third wavelength specification for the vanadate. In addition to AR for 808nm, 1187nm and 1064nm you have to add 1187nm to 1064nm to all the cavity optics as well. This would have been expensive and I decided to work with dyes instead because of the greater wavelength flexibility.

You DID this? Please tell me you at least took some pictures!
Though I agree that dye (and Ti:Sapph) will continue to dominate the tunable field for the near future, I have no doubt that one day dye lasers will become commonplace, especially with the developments we're making with them in both the photonics aspect and manufacturing.
I'm not sure. Dye has the advantage of very low cost as well as tune-ability. The flowing nature of liquid dye allows tremendous average powers to be produced, but since the development of the pyromethene dyes, based on boron fluoride, there has been little research into new higher efficiency dyes. The fact that dyes can operate both as laser pumped and flash lamp pumped systems allows for high energy, ultra fast and high average power systems. This is a rich field to play around in.
I did not take any pictures of my diamond laser, but the fixed yellow color, although nice, was just that, fixed. If YAG lasers were naturally yellow we would get all excited by a green version.
