Could we use LM723 as Current Regulator?

What do you think about lm723?
It is a Voltage Regulator, but we can use it as current regulator?

At this point, I don´t looking for a small driver, but a cheap and efficent alternative to the (good DDL) current regulator.

I tried find something in the Google , but without sucess.

there are sooo many other ways to power a laser, and a bunch of much better, hence more expensive, chips than the Lm317's or 7805's

you just need an automatic current control circuit (ACC), or APC (automatic power control) circuits, google should lead the way from there, and you gotta have good testing equipment too, that way you know the circuit works before testing it on an expensive laser.

Also, I should add, the datasheet: http://www.national.com/ds/LM/LM723.pdf
Tells you everything you need to know to use it too. ;D
