Coherent expands the LightStone family of high-power diode lasers with the 80W LightStone, the highest power diode laser for pumping and direct-diode applications
The new LightStone produces 80W of continuous-wave output at 808nm.
It is the highest power diode laser available for use in direct-diode materials processing and as a pump source for diode-pumped lasers.
As with all LightStone products, the 80W LightStone is based on the industry standard, macro-channel-cooled platform (MCCP).
Due to this unique mounting and cooling technology, LightStone can be stacked vertically or horizontally, making it an ideal building block for applications requiring kilowatts of CW power.
This 90% fill-factor bar has a typical operating current and voltage of 104amperes at less than 2.1volts.
Beam divergence is less than 35deg by less than 10deg, FWHM.
LightStone provides greater than 40% power conversion efficiency, even at elevated temperatures.
The proprietary cooling technology behind LightStone's thermal resistance, which is less than 0.35C/W, is the foundation for the unit's 7000-hour lifetime (20% operating current increase).
Coherent diode lasers are MBE-grown and feature an aluminum-free active area design, which provides robust high-temperature performance, and nearly eliminates dark-line and spot defects, sudden failures and gradual degradation typically found in MOCVD-grown AlGaAs diode lasers.
And since there is no aluminum in the active region of the device, there is no oxidation in the facets - the leading failure mechanism with AlGaAs diode lasers.
