Hamamatsu develops high power QCL module ideal for laser micromachining of fluoropolymer resins

Hamamatsu Photonics has developed a high power QCL module that delivers an average output power of 2 watts at a wavelength of 8.6 micrometers. This high power QCL module was created by applying the company's unique beam combining technology, with quantum cascade lasers (QCL)1, developed based on new heat dissipation technology. This QCL module combines mid-infrared light beams emitted from two QCLs to boost the output power to a level ideal for micromachining of fluoropolymer resins, such as polytetrafluoroethylene (PTFE) that are used for high frequency device substrates, and a vast range of vehicles and transportation machinery. Other potential applications for this QCL module include medical treatment and healthcare.

This new module was designed and developed as part of a project called “Development of Advanced Laser Processing with Intelligence Based on High-Brightness and High-Efficiency Next-Generation Laser Technologies” supported by NEDO (New Energy and Industrial Technology Development Organization), a major national research and development agency in Japan. This QCL module will be shown at the NEDO booth at the OPIE ’21 (OPTICS & PHOTONICS International Exhibition 2021), at the Pacifico Yokohama (Nishi-ku, Yokohama, Japan) for 3 days from Wednesday 30 June to Friday 2 July 2021.

1 Quantum cascade laser or QCL is a semiconductor laser light source utilising a quantum structure for the light-emitting layers to produce high output power in the mid-to-far infrared region.
