چکیده
1.3 μm Nd laser has significant practical applications in various fields, such as fiber communication, medical treatment, frequency conversion, and scientific research, etc. Many of a laser, especially like benefit much from short pulse width with high peak power. In the paper, an electro-optical cavity dumping Nd:YVO<sub>4</sub> at 1342 nm wavelength been studied theoretically experimentally. The for is determined by optical length cavity. A narrower can be obtained reducing round trip time However, when approaches to falling edge switch, shortening will not get width, switch influence width. temporal characteristics are simulated close Influences on duration analyzed theoretically. modified rate equation used study relationship between We demonstrate laser. 0.3 at.% placed Plano-concave in-band pumped 880 quasi-continuous-wave diode. fiber-coupled diode module (NA=0.22) power 30 W was used. LiNbO<sub>3</sub> employed cavity-dumping. cavity-dumping operates repetition 1kHz, single-pulse energy 0.21 mJ 2.8 ns. Near-diffraction-limited beam quality M<sup>2</sup> value < l.2 achieved. setup provides efficient second harmonic generation 671 using MgO:PPLN crystal, 1.8 To best our knowledge, this shortest 1.3μm actively Q-switched Nd-doped

2 980 nm Photonic Microcavity Vertical Cavity Surface Emitting Laser
Vertical-Cavity Surface-Emitting Laser (VCSEL) is a type of semiconductor laser with laser beam perpendicular to the surface of the semiconductor substrate, as shown in Fig.1(a) [1]. VCSEL has many advantages, such as non-divergence output beam, fabrication and test on wafer, easy two-dimensional integration, and single longitudinal mode work. VCSEL is composed of an active region sandwiched be...
متن کاملAbsolute interferometry with a 670-nm external cavity diode laser.
In the past few years there has been much interest in use of tunable diode lasers for absolute interferometry. Here we report on use of an external cavity diode laser operating in the visible (lambda approximately 670 nm) for absolute distance measurements. Under laboratory conditions we achieve better than 1-microm standard uncertainty in distance measurements over a range of 5 m, but signific...

AIM To evaluate the outcome of laser iridotomy using 532-nm Nd: YAG laser (PASCAL) with short pulse duration and Nd: YAG laser compared to conventional combined laser iridotomy. METHODS Retrospective, nonrandomized, comparative case series. Forty-five eyes of 34 patients underwent laser iridotomy. Twenty-two eyes underwent iridotomy using short duration PASCAL and Nd: YAG laser, and 23 eyes u...
متن کاملAutomatic Laser Glare Suppression in Electro-Optical Sensors
Progress in laser technology has led to very compact but nevertheless powerful laser sources. In the visible and near infrared spectral region, lasers of any wavelength can be purchased. Continuous wave laser sources pose an especially serious threat to the human eye and electro-optical sensors due to their high proliferation and easy availability. The manifold of available wavelengths cannot b...
