Coherent Inc. now offers a new line of water-cooled horizontal linear arrays delivering up to 40 W/bar of reliable pump power for side-pumping applications. Utilizing our new PulseLife solder technology, these 2-bar and 3-bar arrays have mean-time-to-failure rates of  >20,000 hours. The unique “macro” channel design requires only simple filtered water and eliminates the complicated water requirements of other water-cooled heat sinks. Standard products at 808 nm in either 80-W 2-bar or 120-W 3-bar congurations are available for pumping applications. PulseLife horizontal arrays can be customized in both power and wavelength for special OEM needs to provide solid-state laser designers with higher levels of performance and reliability.
