Do something like that, but use more life elemnets like wall or balckholes with plasma and clne.
You can make it only glows by making on lcry and adding in center glow on specify temprature.
You can copy my laser and improve or modify, but give the credit.

@TheTempest
Use living gol (constantly replicating) to heat filter and voide to shoot the photons through.
For cold lasers use liquid crystal and dead (not moving) gol to super cool the photons.

@TheTempest
Heating: GoL (fragile, constant heat, lowest temp of all), Plasma (hard to control, random heat), Nuclear (pressure needed, heat builds up, highest possible heat)

Density: The less gaps, the less beam distortion from lava; The more photons per pixels, the stronger the beam.

Cloning: Ensure that most of the clone pixels can create photons and ensure that the photons will all be focused.

@TheTempest
Clone or Powered Clone

Nuclear has highest possible heat but GoL is very effective. It is only about 1000C difference.

Lasers can cause multiple particles to be on a single pixel.

GoL - 9000 degree heat
PCLN - For manually firing the laser
NSCN - On
NSCN - Off
INSL - For keeping the 2 above cool, and to prevent parts melting (quite a problem sometimes)

@TheTempest
Heating In-depth:
Plasma: Heating speed depends on clone speed, can be hard to use, generates slight pressure, requires a draining mechanism, heat drains the most.

Nuclear: Highest possible temp, needs pressure, illegal due to pressure in some competitions, affected by heat drain, uranium is used.

Game of Life: Heats very quickly, compact: a 2x2 unit can heat things up quite quickly, almost no heat loss, the heating rate can be affected by the GoL type used.

Effects

Laser Density: The more particles there are in a pixel, the better the heating.

Transparency: Some materials allow photon to pass through, this causes them to lose heat while taking less damage.

Distortion: If photons hit certain angles, they are removed, this is usually if lava falls on them.

Absorption: Lasers are absorbed by black objects and void. As a result, coal, being black and unmeltable is able to stop lasers.

Invisible: Invisible turns photons into neutrons this can be either good or bad, depending on the circumstances.
