Longitudinal-torsional complex-mode ultrasonic actuator for vibration-assisted drilling of CFRP
Carbon-fiber-reinforced plastic (CFRP) composites are intensively used in aircraft and aerospace industry thanks to their superior properties. Comparing to the conventional drilling (CD), vibration-assisted drilling (VAD) is a novel machining technique ...

High power cladding-pumped Raman fiber laser with true single-mode output at 1660 nm
We report a 10 W continuous-wave cladding-pump Raman fiber laser with single-mode output at 1660 nm pumped by a high-power Er:Yb fiber amplifier. The laser threshold was 6.5 W and its slope efficiency was 67%

Single-mode fiber length for wavefront filtering
Stellar nulling interferometry offers the possibility of direct imaging of extrasolar planets necessary for the detection of extra-terrestrial life. Achieving optimum performance from the interferometers requires that the wavefronts of light reaching the

Tunable Single-Longitudinal-Mode High-Power Fiber Laser
We report a novel CW tunable high-power single-longitudinal-mode fiber laser with a linewidth of ∼9 MHz. A tunable fiber Bragg grating provided wavelength selection over a 10 nm range. An all-fiber Fabry-Perot filter was used to increase the longitudinal
