INNOVA FreD

INNOVA FreD (Frequency Doubled) systems combine the best features of our standard ion laser product lines with wavelength coverage extended into the deep-UV.

FreD lasers use intra-cavity frequency doubling to produce continuous wave laser emission in the 229 to 264 nm wavelength range. This portion of the electromagnetic spectrum provides significant utility in a number of applications, such as fiber-grating manufacturing, UV resonance Raman spectroscopy, and semiconductor applications.

A Deep and Agile Ion Laser

In applications requiring deep-UV, the qualities of the output beam are of the utmost importance. FreD lasers exhibit exceptional spatial and temporal coherence, wavelength stability, and output power stability. These factors make FreD lasers the ideal product for exacting applications requiring precise process control.

Key attributes:

  • Multiline visible output to 20 W, single-line deep-UV to 1 W
  • Each system carries the characteristic features of its parent family
  • I-300C and Sabre models incorporate motorized crystal shifting, which are accessible from the digital remote, or from external computer control

2Fundamental output power is guaranteed for Multiline Visible, 514.5 and 488.0 nm wavelengths. Guaranteed performance at additional wavelengths is

available at a supplementary charge to cover optics (where required) and testing.

3Additional optics and supplementary charge required for guaranteed performance at Multiline UV.

4Beam parameter values are typical.

5Beam diameter measured at 1/e2 points, 1m from output bezel.

6 Beam diameter measured at 1/e2 points at the output coupler.

7Full-angle measurement.

8Performance in light regulation with PowerTrack™ over a 30-minute period following a one-hour warm-up.
