Fiber-Coupled QCW Modules

Dilas has added 500-W water-cooled stacks with a numerical aperture of 0.22 to its line of fiber-coupled laser modules. Providing a quasicontinuous-wave (QCW) operating mode with a duty cycle of up to 30%, the stacks deliver scalable output power up to 500 W at 808, 940 and 976 nm from an 800-µm-core-diameter fiber, resulting in high coupling efficiency. Custom wavelengths are available upon request. The stacks are suitable for medical applications such as hair removal. After a stack is installed in a laser system, the fiber delivers light to the handpiece, rendering it less sensitive to shock and easy to handle. Devices are available with optional features, including an integrated pilot beam, a fiber interlock and a user-exchangeable protection window.
