Nd:YLF Applications
1. Medical applications:
- Ophthalmology: Nd:YLF lasers are employed in procedures such as LASIK (Laser-Assisted In Situ Keratomileusis) for vision correction, as they enable precise reshaping of the cornea.
- Dermatology: They are used for tattoo removal, skin renewal and various dermatological treatments, given that they can specifically target particular pigments and tissues.
2. Scientific research:
- Ultrafast lasers: Nd:YLF lasers support ultrafast laser systems and facilitate research in spectroscopy, microscopy and materials science.
- Pump lasers: They function as efficient pump lasers to generate high-energy pulses in optical parametric oscillators (OPOs) and other laser systems used in research laboratories.
3. Materials processing:
- Marking and engraving: Nd:YLF lasers are employed for precision marking and engraving on materials such as metals, ceramics and plastics.
- Microfabrication: They are utilised in microfabrication, including cutting, drilling and micro-machining.
4. Remote sensing:
- LIDAR (Light Detection and Ranging): Nd:YLF lasers are employed in LIDAR systems for atmospheric studies, remote sensing and topographical mapping, thereby assisting environmental monitoring and research.
