A highly efficient diode-pumped passively mode-locked Nd

In this letter, a diode-pumped passively mode-locked Nd:Lu 1.5 Y 1.5 Al 5 O 12 (Nd:LuYAG) laser is demonstrated for the first time, to the best of our knowledge. With a semiconductor saturable-absorber mirror, a maximum output power of 0.85 W at 1064 nm was obtained under an absorbed power of 8.51 W, corresponding to a high slope efficiency of 44%.

Light Microscopy with Doughnut Modes: A Concept to Detect

Higher order laser modes, mainly called doughnut modes (DMs) have use in many different branches of research, such as, bio-imaging, material science, single-molecule microscopy, and spectroscopy. The main reason of their increasing importance is that recently, the techniques to generate well-defined DMs have been refined or rediscovered.

End-pumped by a diode laser at 970 nm in a hemispherical cavity, a 1.6 W quasi-cw laser at 1.5–1.6 μm with a slope efficiency of 18% and an absorbed pump threshold of 5.9 W was achieved in a 1.8-mm-thick Z-cut Er:Yb:Sr 3 Gd 2 (BO 3) 4 crystal. This crystal has a flat and broad gain curve at 1.5–1.6 μm and so is also a potential gain

Direct generation of a first-Stokes vortex laser beam from

To the best of our knowledge, this is the first report of intracavity stimulated Raman scattering (SRS) being used as a method for frequency conversion of a vortex laser beam and it is effective in enabling the frequency-converted (Stokes) beam to have the same LG01 mode as the fundamental beam.

Growth, structure, and spectroscopic properties of a Cr3

A new laser crystal from Lu 2.4 Y 0.6 Al 5 O 12 (LuYAG) co-doped with Cr 3+, Tm 3+, Ho 3+, and Pr 3+ ions was grown successfully by the Czochralski method for the first time. The structure parameters of the Cr,Tm,Ho,Pr:LuYAG crystal are determined by the X-ray Rietveld refinement method.

Nd:LYAG and Nd:LGAG Mixed Crystals: Potential Candidates

Cooling the laser samples down to about 6 °C, output powers of about 0.56 and 0.46 W with slope efficiencies of about 5.5% and 5.6% can be achieved, respectively, for the two crystals. These Nd3 ± -doped garnet mixed crystals, like single crystal Nd:YAG, are believed to be the potential for laser generation at the important 1.83-μm near
