What is a Tunable Laser and How Does it Work?

[asdf1]

could someone also simply explain what that is? it doesn't have anything to do with a dye, right?

Many organic dyes (yes, real dyes) have broad fluorescence bands. The
tunable dye laser allows you to excite the dye (with a pump laser) and then tune the laser output to the particular wavelength needed. I used one decades ago in doing some atomic beam experiments (the dye used was rhodamine G, if I recall).

Here's a readable tutorial for more details: http://repairfaq.ece.drexel.edu/sam/CORD/leot/course03_mod10/mod03-10.html
