Bistable 1060-nm High-Power Single-Mode DFB Laser Diode

High reliability level on single-mode 980nm-1060 nm diode lasers for telecommunication and industrial applications

We demonstrate very high reliability level on 980-1060nm high-power single-mode lasers through multi-cell tests. First, we show how our chip design and technology enables high reliability levels. Then, we aged 758 devices during 9500 hours among 6 cells with high current (0.8A-1.2A) and high submount temperature (65°C-105°C) for the reliability demonstration. Sudden catastrophic failure is the ...

Treatment of lentigines by a novel high power diode laser at 755 nm: a case report

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...

High-Power Fundamental Mode Single-Frequency Laser

The first results on an injection-locked high-power Nd:YAG ring laser with 195W single frequency output power in a stable linearly polarized fundamental mode operation for the next generation of gravitational wave detectors will be presented. ©2004 Optical Society of America OCIS codes: (140.3520) Lasers, injection-locked; (140.3570) Lasers, single-mode Introduction For the fundamental research...

High-Power DFB Diode Laser-Based CO-QEPAS Sensor: Optimization and Performance

A highly sensitive carbon monoxide (CO) trace gas sensor based on quartz-enhanced photoacoustic spectroscopy (QEPAS) was demonstrated. A high-power distributed feedback (DFB), continuous wave (CW) 2.33 μm diode laser with an 8.8 mW output power was used as the QEPAS excitation source. By optimizing the modulation depth and adding an optimum micro-resonator, compared to a bare quartz tuning fork...
