Optical Communications, vol. 370, pp. 150–155, (2016) Realization and characterization of single-frequency tunable 637.2 nm high-power laser J. Wang, J. Bai, J. He, and J. Wang We report the preparation of narrow-linewidth 637.2 nm laser device by single-pass sum-frequency generation (SFG) of two infrared lasers at 1560.5 nm and 1076.9 nm in PPMgO:LN crystal. Over 8.75 W of single-frequency con...

We describe first the single mode output intensity of a Brewster windowed laser containing isotope mixtures when the cavity tuning is varied, and then the single mode output of a non-Brewster windowed laser under the influence of an axial magnetic field (Zeeman laser). We show how the central tuning (Lamb) dip in intensity gives way to more complicated tuning dependences such as a double dip. F...

background: the effectiveness of low power lasers on incisional wound healing, because of confl icting results of previous studies, is uncertain. therefore, the aim of this study was to evaluate the effects of low-level helium-neon (he-ne) laser irradiation on wound healing in rat’s oral mucosa. materials and methods: sixty-four standardized incisions were carried out on the buccal mucosa of 32...

Background and Objectives: Accelerating wound healing is a very important factor for patients to return to ordinary life. Laser seems to have positive effect on cutaneous wound healing. This study aimed to investigate the effect of red light laser 630 nm on cutaneous surgical wound in hamster and to compare outcomes such as angiogenesis, number of fibroblasts and collagen form...
