It does appear to be Ti:Sapphire, based on the cut and appearance of that crystal.
However the optical layout is different to what I've seen before. Especially that prism triplet.

So this is promising.
I'll see if I can dig up more.
Edit: I've come across a now non-existant PDF of a Titan DQ-100FS Ti:Sapphire Amplifier.
I can't say you have this model, but I can be sure of the fact that you have something along these lines.
The 100FS part of the model refers to 100 femtoseconds (fs).
For me, this device is a mystery. I have only speculations.
on the body of the inscription TITAN.
no labeling.
serial number 11.
that's all what I know
That is a nice laser. Shame there is no more info on it.
What I can determine for you is that this is a Ti:Sapphire laser and is most likely a high gain femtosecond amplifier.
What I can't tell you is the model.
