Waveguide mode filters fabricated using laser-induced forward transfer

Laser-induced Forward Transfer of Ag Nanopaste

Over the past decade, there has been much development of non-lithographic methods(1-3) for printing metallic inks or other functional materials. Many of these processes such as inkjet(3) and laser-induced forward transfer (LIFT)(4) have become increasingly popular as interest in printable electronics and maskless patterning has grown. These additive manufacturing processes are inexpensive, envi...

Laser-Induced Forward Transfer of Pure Metals

Laser Induced Forward Transfer for Materials Patterning

Today, a strong research effort is directed towards the development and integration of new materials, especially of polymers and biomolecules which are essential in pharmaceutical, bioengineering, and sensing applications. In fact, patterning of organic and inorganic materials, in particular enabling precise positioning of different materials with nano and micro scale resolution over large area...

A 100 mW monolithic Yb waveguide laser fabricated using the femtosecond laser direct - write technique

A femtosecond laser-written monolithic waveguide laser (WGL) oscillator based on a distributed feedback (DFB) architecture and fabricated in ytterbium doped phosphate glass is reported. The device lased at 1033 nm with an output power of 102 mW and a bandwidth less than 2 pm when bidirectionally pumped at 976 nm. The WGL device was stable and operated for 50 hours without degradation. This demo...
