Starting a thread with a few questions I have about 1.0.8 lasers:
1. Is there any reason to ever not use two frequency doublers? Rather than purple vs green we might go into near UV vs near UV next.
2. Removing the turrets: my intuition (and of other people) seems to be that this is useful if you have a very maneuverable ship or drone you never intend to get hit. Anyone has examples?
3. Can anyone make a blue laser work? I know it is now theoretically possible (475nm, twice doubled Thulium:Silica Fiber + Krypton) but initial attempts have not been satisfactory. Yes, I realize this is mostly an aesthetic concern.

Now you can make all the colours of the rainbow!
Or you know... near x-ray lasers!

I'm now awaiting someone to make a blue laser.
I NEED IT FOR A REASON!!!

The removal of turrets is interesting, since now it is theoretically possible to put a very large mirror on a reasonably sized ship (the mirror can take up the entire nose cone). I managed to stick a 30m aperture on a roughly 2kt ship with reasonable performance characteristics, though the result looks quite silly. The only problem is it can't hold its nose on target well enough for the laser to fire, RCS thrusters still don't really work.
Might be able to get away with sticking a meter or two of mirror on a drone though.

You might need really REALLY small and weak side thruster for aiming.

I'm now awaiting someone to make a blue laser. I NEED IT FOR A REASON!!! You can make your blue laser by simply using Thulium:Silica Fiber and 2 frequency doublers. If you need a specific power / range I can throw something together real quick if you give me specs to aim for. |

I think trying to get a higher efficiency than 0.5% or so would be neat, that seems to be the limit for my designs at least. I based my blue laser off of a 480MW Green laser I made a while back, and they're identical in output yet the blue has around 0.3% efficiency compared to the greens 3.66%. |

On a side note, this update has me questioning if I want 4x intensity in my lasers at the cost of making them invisible. I like pretty green, violet, or now blue lasers  |

I like pretty green, violet, or now blue lasers I feel your pain but for me there was too huge of an upside to taking the titanium sapphire violets into UV. 4x the intensity at 1,000km which meant I could lower the power draw by 4x which massivly reduced the cost and mass of my 20x laser drones. That along with the Osmium thermocoupler brought their mass/cost down from 211t / 2.11Mc to 117t / 640kc per drone while still maintaining the same MW/m^2 at 1,000km. |

I remember seeing that post and trying to best you with my lasers but it didn't work out lol. This free intensity really makes me wonder why we couldn't have 3, 4, 5, or 42 doublers in series and basically make the death star. |

Some progress: on drones at least, a 22t drone using 4MW MPDs for RCS can carry a 1.6m 3MW laser, and keep it on target enough to carve stock ships up rather nicely. They're not precise enough to component snipe though.
They're also relatively short ranged as lasers go, since they're limited by the precision of their RCS. Still, that huge mirror allows them to do some quite impressive damage with a 3MW laser.
If someone managed to perfect a precise and responsive RCS system for a large ship, it could potentially make quite a doom laser.

If we could get those 4-directional RCS thrusters that look like these  and tweak them to be as large and as powerful as we need, RCS could be really precise but until then, the autopilot will just flail with the thrusters and still manage to be no where near where it needs to be. |

Just to better illustrate how much better laser drones are since the frequency quadroupler was added. The lasers are a about 10% higher intensity and require 4x less power (from gains in pumping by reducing the power input from 100MW to 25MW). It even doubled the delta-v due to less total mass (they still can go up to 300 km/s delta-v if you add enough fuel). Before Patch:  After Patch:  |
