Coherent Diamond J-3-5 (CO Laser 5 µm)

The Coherent Diamond J-3-5 laser is a fully sealed carbon monoxide (CO) laser source representing a new generation of mid-infrared lasers for industrial and medical applications. Thanks to its unique wavelength around 5 µm, it enables much more efficient processing of specific materials compared to conventional CO₂ lasers. An exceptional feature is the ability to achieve extremely small focal spot sizes, delivering unmatched resolution and precision.

5 µm Wavelength

The unique mid-infrared spectrum (5.5 ± 0.25 µm) opens up entirely new possibilities for material processing.

Output Power Above 250 W

Stable power with both pulsed and continuous-wave (CW) operation, and peak pulsed power above 750 W.

Focus Spot Down to 25 µm

Outstanding beam focusability is ideal for precision micro-drilling and highly accurate micromachining.


Key Features

  • Output power >250 W (operating range 10 to 250 W) in the mid-infrared spectrum.
  • Typical peak power reaching ≥750 W.
  • Stable pulsed operation (from single pulses up to 200 kHz) as well as continuous-wave mode.
  • Excellent beam quality (M² < 1.2).
  • Fully sealed design ensuring reliability suitable for long-term industrial operation.
  • Low total cost of ownership, comparable to standard CO₂ lasers.

Product description

The Diamond J-3-5 laser uses innovative CO laser technology and offers a unique combination of high power, exceptional beam quality, and a specific wavelength. This wavelength (5.5 µm) enables very different and often more efficient absorption in selected materials, expanding laser processing capabilities into areas where conventional CO₂ lasers encounter physical limitations.

A key technological advantage of this source is its focusing capability. Achieving a laser beam focal spot as small as 25 µm enables fine micro via drilling and production with exceptionally high resolution.

In the past, CO laser technology was limited by short lifetime and impractical operating characteristics. However, Coherent’s technological breakthroughs have removed these barriers. Today, the fully sealed Diamond J-3-5 platform offers industrial reliability, lifetime, and maintenance requirements fully comparable to proven CO₂ lasers.
