First Diode-Pumped Samarium Laser in the Visible Range
Development of the first diode-pumped samarium laser emitting in the visible range, operating at 605 nm in the orange spectrum.

Alongside researchers from the National Graduate School of Engineering of Caen, Oxxius’ team contributed to the development of the first diode-pumped samarium laser emitting in the visible range. This novel laser, operating at 605 nm in the orange spectrum, offers exciting possibilities for flow cytometry, laser guide stars for astronomy, and ozone gas detection.
Key highlights from the research:
- First-ever visible orange samarium laser directly pumped by a blue GaN semiconductor laser diode
- Uses LiYF₄ (lithium yttrium fluoride) crystals, known for superior thermal and optical properties
- Delivers 23.9 mW continuous-wave output at 605 nm
- Potential for higher efficiency and power scaling with optimized doping and crystal design.
