>> the hottest laser beam is about 1000 degrees Celsius (1832 F)

Technically a laser beam doesn't have a temperature since it is made of photons and not matter. Temperature is related to the average vibrational energy of the atoms in a chunk of matter. No vibrating atoms means temperature can't be measured.

However a laser beam of the right frequency can easily heat something up far hotter 1000 C. Laser beams routinely vaporize steel, which boils at 3000 C (5432 F), and tungsten which boils at over 5550 C (10022 F). This approaches the surface temperature of the Sun, 5800 C or 10472 F.

The biggest laser in the world, actually 192 lasers all focused on the same spot, is at the National Ignition Facility in Livermore California. They recently dumped 1 Megajoule of energy into a target a few mm across over a period of a few nanoseconds. They are shooting for temperatures of 200,000,000 F (111,111,093 C) in order to induce nuclear fusion in a frozen hydrogen pellet.

So I you could say that the hottest laser in the world can produce temperatures of around 111,000,000 C or 200,000,000 F which is about 7 times the temperatures estimated for the inside of the Sun; 30,000,000 F or 16,666,648.9 C.

it depends on what strength you have.

5mw-60mw - nothing

65mw-80mw - meh, bit of heat

95-125mw - stings, probably get a burn

130mw-150mw - ouch! HAWT! HAWT!

155mw-300mw - I was stupid enough to do this

A semi conductor laser can get very hot especially if it is not handled properly. You need to be careful when adjusting the setting and make sure to not let the heat of the laser enter into someone eye where it can sunburn the cornea.
