Single-longitudinal-mode optical parametric oscillator for spectroscopic applications [PDF]
Optics Letters, 2002 We have developed a tunable, narrow-bandwidth nanosecond optical parametric oscillator system and applied it to spectroscopic studies. The system consists of a narrow-bandwidth grazing-incidence oscillator and a seeded power oscillator, generating Fourier-transform-limited 1.5-ns pulses (bandwidth

High power cladding-pumped Raman fiber laser with true single-mode output at 1660 nm
, 2006 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
, 2008 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
