A high-average power, laser-diode-pumped, picosecond-pulse regenerative chirped pulse amplifier was developed by using the thin-rod Yb:YAG laser architecture. An average output power of 20 W was achieved at a repetition rate of 100 kHz with an output pulse width of 2 ps. 2008 Optical Society of America OCIS codes: (140.3280) Lasers, amplifiers, (140.3615) Lasers, ytterbium, (140.3480) Lasers, ...

used in conjunction with or as a replacement for traditional methods, it is expected that specific laser technologies will become an essential component of contemporary dental practice over the next decade. the current review is designed to focus on the acid resistance of laser application and tries to introduce laser settings capable to achieve this feature for clinical application. applicatio...

The wide range of available wavelengths, high brightness and increasing reliability are breaking new ground for diode lasers. Material processing with high power diode lasers in industrial manufacturing is getting more and more important. In automotive, medical device and also solar cell production they are important tools for automated production. Closed-loop temperature control by integrated ...

High power high brightness diode lasers are gaining more and more interest for applications previously dominated by expensive and inefficient solid-state lasers due to their better efficiency, brightness and compactness. The significant fact about conventional high brightness optical sources is that they exhibit about an order of magnitude higher brightness than broad-area semiconductor lasers....

The development of compact spectroscopic gas sensors and their applications to environmental sensing will be described. These sensors employ mid-infrared difference-frequency generation (DFG) in periodically poled lithium niobate (PPLN) crystals pumped by two single-frequency solid state lasers such as diode lasers, diode-pumped solid state, and fiber lasers. Ultrasensitive, highly selective, a...

Introduction The development of laser diodes has increased the variety of practical applications for lasers as light sources in analytical spectroscopy. Lasers are excellent radiation sources due to their monochromaticity, good beam focusing capabilities, and small line-widths but have traditionally been expensive and difficult to operate, limiting their applications to specialized fields. Beca...

The use of high-power diode laser with a wavelength of 755 nm is an effective and safe method for the correction and partial and/or total elimination of pigmented lesions, specifically solar lentigines. This wavelength has yet not been used in diode lasers to treat solar lentigines. Side effects are the usual ones, including darkening and scab formation. Our patient was a 40-year-old woman of C...

We propose a technique to simultaneously stabilize relative wavelengths among multiple diode lasers by using multiplexed photorefractive gratings. Each grating is designed to be Bragg matched for the counter-propagating reflection at a specific diode laser wavelength. Experimental results from stabilization of two diode laser wavelengths by using two photorefractive gratings exhibit excellent s...

We present a new approach for extended-cavity diode-laser tuning to achieve wide mode-hop-free tuning ranges. By using a multiple piezoactuated grating mount, the cavity length and grating angle in the laser can be adjusted independently, allowing mode-hop-free tuning without the need for a mechanically optimized pivot-point mount. Furthermore, synchronized diode injection-current tuning allows...
