Ultrafast femtosecond mode-locked fiber laser plays an indispensable role in medical
imaging, space ranging, ophthalmology, terahertz spectroscopy, material micromachining …

We propose and demonstrate a new approach to implement a wavelength-tunable ultrafast
fiber laser source suitable for multiphoton microscopy. We employ fiber-optic nonlinearities …

Moving the fiber laser emission to the region below one micron may provide a cheaper,
more compact and robust alternatives to the existing solid state lasers. Here, for the first time …

In two-photon microscopy, low illumination powers on samples and a high signal-to-noise
ratio (SNR) of the excitation laser are highly desired for alleviating the problems of …

We report a single-frequency distributed Bragg reflector (DBR) fiber laser at 930 nm for the
first time, to the best of our knowledge. A∼ 2.5 cm long commercial highly neodymium …

We present a compact passively mode-locked fiber laser emitting near 910 nm with an all-
polarization-maintaining fiber laser architecture. The ring-cavity laser configuration includes …

A femtosecond all-PM-fiber Mamyshev oscillator (MO) at 920 nm is presented. It is based on
a neodymium-doped fiber with a W-type index profile that effectively suppresses the …

We present a comprehensive study of dispersion managed ultrashort-pulse generation in
Nd-doped polarization maintaining all-fiber laser at a 920 nm wavelength. We implement a …

We demonstrate a femtosecond all-polarization-maintaining Nd fiber laser working at 920
nm mode locked by a biased non-linear loop mirror. The broadest spectral width of the pulse …

Pre-chirp technique was used in an Nd-doped fiber amplifier to optimize high-quality 910 nm
pulses with the pulses width of 114 fs and pulse energy of 4.4 nJ. The in vivo zebrafish …
