Long ring-cavity, all-polarization maintaining, Er-doped fiber laser using single wall carbon nanotube polyimide film was demonstrated. Output pulses with pulse energy of 0.7∼2.6 nJ were obtained at ultra low repetition rate of 943∼154 kHz.
All-polarization maintaining Er-doped ultrashort soliton fiber laser using single wall carbon nanotube polyimide film and variable output coupler is constructed and investigated. A 580 pJ and 46 fs ultrashort pulse is generated after compression.
Quasi super continuum generation at 1.1-1.4 mum is demonstrated using ultrahigh speed wavelength tuning of femtosecond soliton pulses for the first time. The center wavelength, bandwidth, and spectrum shape can be changed arbitrarily.
Quasi super continuum generation for ultrahigh resolution optical coherence tomography is demonstrated using ultrahigh speed wavelength tuning of femtosecond soliton pulse. In this light source, center wavelength, bandwidth, and spectrum shape can be changed arbitrarily.
High power Yb-doped fiber laser amplifier, self-pulsing is problem for instability and optical damage. Simple ring type resonator was consisted to observe the self-pulsing. The sustained self-pulsing observed in room temperature (RT) was restrained in liquid nitrogen temperature (LNT).
A liquid-cooled ceramic Nd:Cr:YAG split-disk laser amplifier have been designed and demonstrated for high-average-power laser system. The maximum small-signal gain of 2.27 and the stored energy of 11.4 J were obtained. The Nd:Cr:YAG showed 1.3 fold amplification efficiency than Nd:YAG.
This paper demonstrates Yb fiber pulse amplifier with stimulated Brillouin scattering phase-conjugating mirrors (SBS-PCM). A linearly polarized amplified laser with low SBS threshold and nearly diffraction-limited beam is achieved by SBS-PCM operation.
We have demonstrated a split-disk laser amplifier with the largest ceramic Nd:Cr:YAG of 70 times 40 times 10 mm dimensions. One pass gain and total stored energy were 2.27 and 11.4 J, respectively.
Self mode-locked Ytterbium-doped fiber (YDF) ring-laser is presented that consisted of all polarization-maintaining (PM) fiber system, especially single-mode PM-YDF with side-hole type. Environmentally stable pulses and a wide tuning range of 60 nm were obtained.
In this paper, we report on a simple ytterbium-doped-fiber (YDF) pulse laser with a Fabry-Perot resonator. This fiber laser oscillator consisted of FBGs (fiber Bragg gratings) instead of conventional mirrors. This pulse laser requires neither polarization control nor compensation of birefringence and intracavity dispersion. To our knowledge, the YDF oscillator described here is the simplest composition
