Buried waveguide in neodymium-doped phosphate glass obtained by femtosecond laser writing using a do
[期刊论文] 作者：XuewenLong,JingBai,XinLiu,WeiZhao,GuanghuaCheng,
来源：ChineseOpticsLetters 年份：2013
We fabricate a buried channel waveguide in neodymium-doped phosphate glass using a double line approach by femtosecond laser writing. Raman spectra reveal an expansion of the glass network in the laser irradiated region. Given the stress-in......

The writing of an internal diffraction grating in optical glass plate is demonstrated using low-density plasma formation excited by a high-intensity femtosecond Ti:sapphire laser. The same diffraction efficiency at -1, -2, and 0 order isa......

We report a simple approach to amplify Ti:sapphire femtosecond pulses to moderate energy levels by a chirped regenerative amplifier. The seed pulses are broaden naturally because of the material dispersion of system components in regenerati......
Ultrashort Bessel beam photoinscription of Bragg grating waveguides and their application as tempera

Ultrashort pulsed Bessel beams with intrinsic nondiffractive character and potential strong excitation confinement down to 100 nm can show a series of advantages over Gaussian beams in fabricating efficient Bragg grating waveguides (BGWs). ......
Three-dimensional optical data storage using a solid immersion lens to focus a femtosecond laser pul
