Green Lasers
SANTA CLARA, Calif., Dec. 15, 2009 – Coherent Inc. has launched the next generation of diode-pumped solid-state continuous-wave lasers. The Verdi G-Series is available in both 2- and 5-W green (532 nm) versions. By replacing the conventional gain medium with an optically pumped semiconductor structure, the company has made a more robust, wavelength-flexible and compact source suited for scientific applications, including pumping of ultrafast and continuous-wave Ti:sapphire lasers. The devices have a 50% smaller footprint than previous Verdi models and a lower price and operating cost, and they offer the ability to use other wavelengths.
The all semiconductor-based lasers are powered by proprietary AAA (aluminum-free active area) diodes and the company’s patented OPSL (optically pumped semiconductor laser) technology and its PermAlign solder-down platform.

Spectral purity is >99%, spatial mode is TEM00, beam quality is M2 <1.1, and noise is <0.03% rms. The CDRH-compliant lasers operate at temperatures from 10 to 40 °C. Beam pointing stability is <2µrad/°C, warm-up time is <10 min, power consumption is 500 W, and operating voltage is from 100 to 240 VAC.

Applications include spectroscopy, holography, interferometry, carrier envelope phase stabilization, atom cooling and trapping, semiconductor inspection, lithography and micromaterials processing.

The optical recording of the object wave formed by the resulting interference pattern of two mutually coherent component light beams. In the holographic process, a coherent beam first is split into two component beams, one of which irradiates the object, the second of which irradiates a recording medium. The diffraction or scattering of the first wave by the object forms the object wave that proceeds to and interferes with the second coherent beam, or reference wave at the medium. The resulting...
The study and utilization of interference phenomena, based on the wave properties of light.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
