Femtosecond Laser Integrates Optics in Single Glass Substrate for Easy Manufacture
LAUSANNE, Switzerland, Oct. 16, 2023 — The short, regular pulses of femtosecond lasers are put to effective use in numerous applications, including laser surgery, micromachining, microscopy, and spectroscopy. Free-space optics offers substantial freedom in femtosecond laser design — but this comes at the cost of limited miniaturization and manufacturability. A new approach, developed at École Polytechnique Fédérale de Lausanne (EPFL), makes the free-space optical components of a
