and just how much mass will you be accelerating and how will you be using this laser sail? I think this concept is seriously flawed.

Well I will be using multiple lasers so I presume that smaller lens could do the same job...
Well the helium was supercooled and it was pretty close to superfluid so I just made it superfluid...
Well I don't remember the exact weight as I am using my phone but it was relatively light...
Well my craft is suppose to travel at at peak speed of 0.5c so...
If you want to brake then you need to start braking almost before you launch to the target system!
the only interstellar probe project thats being looked at today is Icarus which is a follow on to Daedalus and they are targeting .07c

I hope they don't mind everyone in the program being dead by the time the probe sends its data back. :dry:
Lasers in sol? Like, in the Sun? Ouch.
Do you realise the scale of everything going on here? If you had 'a couple' of lasers, they would have to be absolutely gigantic.
How do you propose to slow the craft down?
How are you going to return the craft to the solar system if there is no gigantic battery of lasers at the starting point?
The batteries will still be gigantic it's just they won't be that powerful... Even if it takes a little longer I still want them back for reuse...
Isn't actually Helium already superfluous if it is just liquid? I have problems imagining conditions in which Helium in your spacecraft would not be superfluous. (Pun intended actually)
I meen the sol system...

Well I seen liquid helium transition into superfluid and if there is a transition there is more than one state.

So if the batteries are gigantic and not powerful what is the point? Surely less batteries (less mass) is better? Why would you even need gigantic batteries? Surely the heat from the fusion drive would be enough to keep the batteries charged?
And of what use is that in space?
In the shuttle fuel is feed into pumps via gasseous helium expanding into the tank to push the fuel. There is no reason an intersteller probe couldn't use the same technique or it could use ullage motors or it could use fusion pellets.
