TL;DR: Depth-resolved cathodoluminescence at 80 K was used to investigate the effects of substrate impurities, Cd or Te coimplants, and Cd-vapor prefiring treatments on the defect reactions that occur in pulsed laser annealing of shallow implants in CdTe as mentioned in this paper.
Abstract: Depth-resolved cathodoluminescence at 80 K was used to investigate the effects of substrate impurities, Cd or Te coimplants, and Cd-vapor prefiring treatments on the defect reactions that occur in pulsed laser annealing of shallow implants in CdTe (Cs+ in CdTe: In, As+ in CdTe: Cl). Implantation into either substrate produces strong nonradiative (<1 eV) defect introduction in the ion range zone (calculated RP =300−440 A). Less severe defect introduction proceeds further to depths on the order of 1 μm into the postrange zone. Pulsed (20 ns) ruby laser annealing was performed at energy densities of 0.16−0.32 J/cm2, with calculated melting depths estimated to be £400 A. In the case of CdTe: In, laser annealing typically promotes a strong defect reaction leading to prominent luminescence near 1.17 eV. Despite the shallowness of the laser melt, this reaction follows the postrange damage to depths approaching 1 μm beyond the projected ion range. We conclude that the 1.17 eV band results from the reacti...

TL;DR: The Q-switched Nd:YAG laser is more effective at tattoo lightening for Chinese individuals after a single treatment, and its immediate response after treatment is slighter than the Q- Switched ruby laser.
Abstract: Background: Black and blue are two popular colors in Chinese tattooing. Two Q-switched lasers, ruby and Nd:YAG, are effective for tattoo removal. No reference with regard to a comparison of the effects and adverse reactions in Chinese individuals has been made in the literature. Objective: To compare a single treatment of black-blue tattoos with the Q-switched ruby laser and Q-switched Nd:YAG (1064 nm) laser. Methods: A total of 35 Chinese patients with black-blue tattoos at the laser center of the Institute of Dermatology, Chinese Academy of Medical Sciences were enrolled into a self-control study. Tattoos were split into two parts or two nearby tattoos on the same body part were used; one side was treated with the Q-switched ruby laser and the other with the Q-switched Nd:YAG laser. Immediate response, treatment outcome and adverse effects were compared. The statistical significance level was set at p< 0.05. Results: Edema and exudation were more common immediately after ruby laser treatment (p<...

TL;DR: In this article, the authors report a woman who developed terminal hair growth at the site of a full thickness skin graft and describe her successful treatment with the normal mode ruby laser, which achieved a reduction in hair numbers sustained on follow-up.
Abstract: Background and Objective
Treatment of hirsutism is often unsatisfactory with many of the currently used methods providing only temporary improvement. The use of lasers for hair removal has shown promising results and treatment by using the normal mode ruby laser has provided reduction in hair numbers sustained on follow-up. We report a woman who developed terminal hair growth at the site of a full thickness skin graft and describe her successful treatment with the normal mode ruby laser. Lasers Surg.
