The use of the Er:YAG 2940nm laser associated with amorolfine lacquer in the treatment of onychomycosis [PDF]

Anais Brasileiros de Dermatologia, 2013
Onychomycosis is a common disease, accounting for up to 50% of all ungual pathologies. We have been developing a clinical trial (ClinicalTrials.gov: NCT01528813) using a 2940nm Er:YAG laser to fractionally ablate human nails in vivo, aiming to increase ...

InGaN-LD-Pumped ${\rm Pr}^{3+}$: ${\rm LiYF}_{4}$ Continuous-Wave Laser at 915 nm

IEEE Photonics Journal, 2014
We demonstrate the first InGaN-LD-pumped room temperature and continuous-wave laser operation of a Pr3+: LiYF4 crystal at 915 nm. A maximum output power up to 78 mW with a laser slope efficiency of about 17% is obtained. The round-trip optical losses are

Cryogenically-cooled Ho:YAG laser in-band pumped by a Tm fibre laser [PDF]

, 2009
Scaling of laser power and brightness to meet the needs of ever-demanding applications is a demanding task which continues to preoccupy many within the laser community. In conventional 'bulk' solid-state lasers the main obstacle is heat generation in the

Generation of a 578-nm Yellow Laser by the Use of Sum-Frequency Mixing in a Branched Cavity

IEEE Photonics Journal, 2016
A compact, continuous-wave, solid-state laser at 578 nm has been demonstrated, for the first time to our knowledge, by use of intracavity sum-frequency mixing from a branched cavity with an LBO crystal. Two gain mediums, namely, the Nd:YAG single crystal

All-optical intensity noise suppression for solid-state and semiconductor lasers

Journal of Telecommunications and Information Technology, 2005
This paper will report on a new all-optical technique of relative intensity noise (RIN) suppression for solidstate and semiconductor lasers. The new scheme we have used is based on an unbalanced Mach-Zehnder interferometer (UMZI), which is able to ...
