Lasers that designate 270W 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.
The JOLD-Open Heatsinks Series are high quality high power laser diode bar products. They are available in a range of open heatsinks including the CS, CN, and LK package. And in wavelengths from 780nm – 1064nm.
