An index-guided red diode laser.

Double-Active-Layer Index-Guided InGaAsP-InP Laser Diode

A buried crescent InGaAsP-InP laser with two active layers was fabricated to study the temperature behavior of the doublecarrier-confinement structure. An anomalously high-characteristic temperature To was measured and an optical switching behavior was observed. A model analysis and numerical calculation using a rate equation approach explained qualitatively very well the experimental results. ...

An Extended Cavity Diode Laser in Red Wavelengths

Optical coherence tomography-guided laser microsurgery for blood coagulation with continuous-wave laser diode

Blood coagulation is the clotting and subsequent dissolution of the clot following repair to the damaged tissue. However, inducing blood coagulation is difficult for some patients with homeostasis dysfunction or during surgery. In this study, we proposed a method to develop an integrated system that combines optical coherence tomography (OCT) and laser microsurgery for blood coagulation. Also, ...

Effect of Low Frequency Low-Level Infra-Red Diode Laser Therapy on Third Degree Burn Healing in Rats Skin

Purpose: The aim of present investigation was to evaluate low frequency low-level infra red diode laser therapy for a third degree burn healing in rats skin.Materials and Methods: 36 rats were divided into groups one and two. On day zero three third degree burns were made on the dorsum of each rat by steam. In group one ,first burn were exposed to a 80 Hz –pulsed 890 nm infra red diode laser wi...
