introduction: pyogenic granuloma (pg) is one of the inflammatory hyperplasia seen in the oral cavity. it is a reactional response to minor trauma or chronic irritation. the most common treatment of pg is surgical excision but alternative approaches such as laser excision have also been proposed especially for pediatric patients. case report: herein, we present a case of gingival pyogenic granul...

We report the basic luminescence properties and the continuous-wave (CW) laser operation of a Pr(3+)-doped KYF(4) single crystal in the Red and Orange spectral regions by using a new pumping scheme. The pump source is an especially developed, compact, slightly tunable and intra-cavity frequency-doubled diode-pumped Nd:YAG laser delivering a CW output power up to about 1.4 W around 469.1 nm. At ...

High-power laser-diode arrays, which are made of stacks of individual or multistripe laser diodes, or in some cases vertical-cavity surfaceemitting lasers (VCSELs), can put out watts to kilowatts of optical power for uses such as laser pumping, industrial heating, illumination, or as the input for fiber-optic direct-diode laser devices for materials processing or for medicine. Laser diodes typi...

BACKGROUND Alexandrite (755 nm) and diode lasers (800-810 nm) are commonly used for hair removal. The alexandrite laser technology is somewhat cumbersome whereas new diode lasers are more robust. Recently, alexandrite-like 755 nm wavelength diodes became available. OBJECTIVES To compare the efficacy, tolerability, and subject satisfaction of a 755 nm diode laser operated in conventional (HR) ...

Volume Bragg gratingTM (VBGTM) technology has been shown to improve spectral characteristics of the high-power laser diodes and arrays. We review the recent advances in VBG technology that lead to better spectral performance as well as improvements in spatial brightness of the high-power laser diode arrays. The VBG technology has been applied to manufacturing of high-power laser diode arrays su...

6 Conclusion 23 Acknowledgments 23 Abbreviations and Acronyms 23 Related Articles 24 References 24 Modern diode laser spectroscopy is becoming an important and a more widely used tool for detection and measurement of trace gases. The change is driven by the recent advances in diode laser technology and diode laser frequency conversion techniques, which now push the limits of emission wavelength...

OBJECTIVE We previously showed that photoablative laser therapy followed by multiple photodynamic cycles (PAPD) after scaling/root planing (SRP) improved healing of periodontitis patients as compared with conventional SRP after 1-year follow-up. This study reports the favorable results of PAPD plus SRP in patients with chronic periodontitis at a 4-year follow-up. MATERIALS AND METHODS Twenty-...
