Using Plantain Rachis Fibers and Mopa-Mopa Resin to Develop a Fully Biobased Composite Material. [PDF]
Polymers (Basel)A completely biobased composite material was developed using a matrix of natural resin extracted from the Elaegia pastoensis Mora plant, commonly known as Mopa-Mopa or “Barniz de Pasto”, reinforced with fibers extracted from plantain rachis agricultural residues.

The Story of Elaeagia Resin (Mopa-Mopa), So Far
Heritage, 2023 The unusual resin from some species of Elaeagia, a genus now found in certain parts of Central America and South America, was probably first utilized by native peoples in Colombia more than a thousand years ago. It became a crucial part of often elaborately decorated objects made in the southwestern city of Pasto in the colonial period, and it has ...

2-kW Average Power CW Phase-Conjugate Solid-State Laser [PDF]
, 2007 We have demonstrated stable operation of a 2-kW Yb:YAG phase-conjugate master oscillator power amplifier (PC-MOPA) laser system with a loop phase-conjugate mirror (LPCM). This is the first demonstration of a continuous wave (CW)-input LPCM MOPA operating

Femtosecond pulses at 50-W average power from an Yb:YAG planar waveguide amplifier seeded by an Yb:KYW oscillator [PDF]
, 2012 We report the demonstration of a high-power single-side-pumped Yb:YAG planar waveguide amplifier seeded by an Yb:KYW femtosecond laser. Five passes through the amplifier yielded 700-fs pulses with average powers of 50 W at 1030 nm. A numerical simulation

A traveling-wave THz photomixer based on angle-tuned phase matching [PDF]
, 1999 A traveling-wave THz photomixer based on a free-space optical-THz phase-matching scheme is proposed. A dc-biased coplanar strip line fabricated on low-temperature-grown GaAs serves as the active area of the device, and is illuminated by two noncollinear ...
