250mW Lasers

What are 250mW Lasers?

Lasers that designate 250mW (0.25W) of output power can have either CW (continuous wave) or pulsed output. CW Lasers are always defined in average output power. Pulsed Lasers with an output power defined in Watts or Milliwatts usually define the laser’s average power, not the peak power of the laser.

Our 250mW Laser Products

RPMC Lasers offers several laser configurations rated for 250mW of average output power, including single emitter laser diodes, laser diode modules, VCSEL diodes (vertical-cavity surface-emitting laser diodes), and pulsed DPSS lasers. These 250mW laser configurations are available in UV, violet, green, yellow, red, and NIR wavelengths, perfect for various applications like confocal fluorescence microscopy, DNA sequencing, flow cytometry, thin film removal, laser texturing, peening & scribing, pulse oximeter integration, and more!

If you do not see exactly what you need among our standard configurations, please contact RPMC to ask about customization options. We can even provide a fully customized solution, tailored to your exact application specifications.
