L4 Family

Accuracy, Configurability, Size

  • Industry’s only precision 1 watt CO2 laser
  • High Stability L4S available
  • Grating Tunable (L4G) from 9.3µm – 10.8µm
L4 Base Features

  • 1 watt CW power
  • Almost Perfect Beam Quality M2=1.1
  • Small foot print, big performance

L4S Features

  • All the features of the L4 with +/- 2% stability
  • Wavelength Tunable from 10.3-10.8 (µm)

L4G Features

  • All the features of the L4 with wavelength tuning
  • Wavelength Tunable from 9.3-10.8 (µm)

Small in size while big in performance, the L4 laser family provides the ideal solution for applications needing less power but higher precision in a compact package. With the same Access Laser optimized resonator design as in the higher power lasers producing a virtual perfect M² = 1.1 beam, high precision applications in thin film processing, interferometric measurement, and spectroscopy achieve the needed performance in a small cost effective package.

Where even higher stability is needed, customers can choose the L4S with a stability of +/-2% or add the Line Tracker Option to get to +/-1% with no line hopping, The L4S with line tracker creates a single wavelength power stable pure reference source.

In applications that also need a single specific wavelength, the L4G configuration provides the laser industry’s smallest tunable CO2 source. With grating tuning from 9.3 μm to 10.8 μm in a fan cooled package the L4G is a leading edge laboratory instrument.

Access Laser specializes in making custom lasers to fit our customers exact needs, numerous other options are available including:
