Femtosecond Laser Ablation of Sapphire

INSTRUCTION Sapphire is widely used in the field of optical components and micromechanical devices owing to its useful mechanical, optical, and electrical properties. However, sapphire is mechanically and chemically difficult to machine because of its high hardness and chemical stability. The difficulty of machining sapphire has restricted the development of advanced device structures. As sapph...

Orthogonally polarized dual-wavelength Nd:LuVO4 laser at 1086 nm and 1089 nm.

A comparison between the fluorescence spectra of the Nd-doped vanadate crystals (Nd:YVO4, Nd:GdVO4, Nd:LuVO4) for the 4F3/2 → 4I11/2 transition is studied. We numerically analyze the condition of gain-to-loss balance via an uncoated intracavity etalon to achieve the dual-wavelength operation. We further experimentally demonstrate the orthogonally polarized dual-wavelength laser with a single Nd...

Alternate Wavelength Switching in a Widely Tunable Dual-Wavelength Tm3þ-Doped Fiber Laser at 1900 nm

We demonstrate alternate wavelength switching in a widely tunable, dualwavelength Tm3þ-doped fiber laser operating at 1900 nm. A comb filter based on a Sagnac loop incorporating a length of high-birefringence fiber is used to define the lasing wavelengths. By simple variation of a polarization controller within the laser cavity, alternate and sequential switching between singleand dual-waveleng...
