TL;DR: In this article, a lensed fiber for high efficiency coupling between a singlemode fiber and a high-power laser diode with large astigmatism of 176 /spl mu/m is proposed and demonstrated.
Abstract: A novel lensed fiber for high-efficiency coupling between a single-mode fiber (SMF) and a high-power laser diode (LD) with large astigmatism of 176 /spl mu/m is proposed and demonstrated. We experimentally confirmed that the proposed lensed fiber had a minimum coupling loss of 2.5 dB including a reflection loss of 0.3 dB at both ends of the fiber. In addition the new configuration had a long working distance of 67 /spl mu/m. We also investigated the tolerance characteristics for various displacements.

TL;DR: In this paper, the authors applied magnetically triggered phase transition of the hydrogel as a chemomechanical device and found that the initial rates of stress generated by the gels prepared in water and in 0.8 M NaCl at 22°C were 0.04 and 0.75 kPa s −1, respectively.

TL;DR: In this paper, magnetic heating was applied to convert magnetic energy into chemomechanical work by using poly(N-isopropylacrylamide), poly (NIPAAm) gel, exhibiting a reversible swellingshrinking property.
Abstract: Magnetic heating was applied to convert magnetic energy into chemomechanical work by using poly(N-isopropylacrylamide), poly(NIPAAm) gel, exhibiting a reversible swellingshrinking property. y-Fe2O3, which can generate heat by itself due to hysteresis loss in the presence of an alternating magnetic field, was immobilized within poly(NIPAAm) gel. The shrinking rate of the hydrogel accelerated when the inner temperature of the gel was increased over 34°C, the lower critical solution temperature (LCST). The initial rate of the temperature increase, which was in proportion to the amount of immobilized ferromagnetic powder, was 0.2°C/s in the gel immobilized 24% of the y-Fe2O3 weight under the alternating magnetic field (effective value 830 Oe, maximum value 1,170 Oe, 2.08 kHz). Cylindrical poly(NIPAAm) gel rods immobilized 24% y-Fe2O3, which was crosslinked by 5% N,N'-methylenebisacrylamide, were able to generate mechanical force. Five gel rods whose cross-area was 1.5 x 10-1 cm2 at 22°C could lift 20 g of wei...
