INTRODUCTION Trichophyton rubrum is one of the most common species of dermatophytes which affects superficial keratinous tissue. It is not especially virulent but it can be responsible for considerable morbidity. Although there are different therapeutic modalities to treat fungal infections, clinicians are searching for alternative treatment because of the various side effects of the present th...

A Master Oscillator Power Amplifier configuration using a Nd:YAG single-crystal fiber to amplify a passively Q-switched microlaser is presented. We achieved the amplification of 80 μJ, sub-nanosecond pulses to the multi-millijoule regime. OCIS codes: (140.3580) Lasers, solid-state; (140.3480) Lasers, diode-pumped; (140.3530) Lasers, neodymium; (140.3380) Laser materials; (060.2290) Fiber materi...

We demonstrate a dual-band Tm:ZBLAN fiber ring laser with synchronized Q-switched pulses and a dual-band simultaneous mode-locked Tm:ZBLAN fiber linear laser at 1.48 μm and 1.85 μm using a common graphene saturable absorber. OCIS codes: (060.2390) Fiber optics, infrared; (140.3540) Lasers, Q-switched; (140.4050) Mode-locked lasers

Post inflammatory hyperpigmentation (PIH) developing after cosmetic procedures, such as chemical peeling and laser therapies, are always a concern, especially in Asians. Some cases of PIH tend to be spontaneously regressed; however, certain forms of PIH need to be treated with several therapeutic attempts, including bleaching creams, several kinds of Q-switched lasers, and erbium-doped fraction...

We study a coupled cavity laser configuration where a passively Q-switched Nd:YAG microchip laser is combined with an extended cavity, including a doped multimode fiber. For appropriate coupling levels with the extended cavity, we observed that beam self-cleaning was induced in the multimode fiber thanks to nonlinear modal coupling, leading to a quasi-single mode laser output. In the regime of ...
