1.75W Lasers

What are 1.75W Lasers?

Lasers that designate 1.75W 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.

LDX Series

The LDX Series of high power multimode single emitter laser diodes include wavelengths of 400nm – 1900nm. Available in a wide range of output powers and package types.

Q2HE Series

Quantas-Q2HE-211: High energy, compact, nanosecond, DPSS laser

The Q2HE series, from Quantum Light Instruments Ltd., features an innovative water-free laser crystal cooling technology that enables generation of high quality laser beams with up to 100 mJ pulse energy and/or up to 4 W of average output power. Featuring a pulse duration of less than 7 ns and a low beam divergence, the Q2HE is capable of achieving efficient fundamental wavelength conversion through the 5th harmonics of 213/211 nm.
