The Stellar-Pro Select 300 from Modu-Laser is an Argon Laser that operates at 457.9 nm, 488 nm, 514.5 nm, and multi-line wavelengths. It deliver maximum output powers of 16 mW (at 457.9 nm), 80 mW (at 488 nm), 100 mW (at 514.5 nm), and 300 mW (at multi-line). This laser produces a beam of diameter 0.75 mm and has a beam divergence of 0.95 mrad. It has TEM₀₀ mode with a beam-pointing stability of up to 30 μrad and polarisation extinction ratio above 250:1. This air-cooled laser has a beam amplitude noise of 1% RMS and output power drift of ± 1%. It requires an AC supply voltage of 200 V - 265 V and consumes up to 3000 W of power. This laser is available in a module that measures 19.2" x 7.6" x 5.4".
