- 3. www.civan.co.il Coherent Beam Combining(CBC) Technology Civan’s lasers are based on Coherent Beam Combining (CBC) technology. CBC principle of operation: • Divide • Amplify • Combine
- 4. www.civan.co.il OPA – OpticalPhased Array • CBC in the far field • Beam overlap and create an interference pattern • By controlling the individual phases the beam position and shape can be modified
- 5. www.civan.co.il What we do SMCBC - High Power in Single Mode beam (up to 10’s of kW) • High power density, Remote operation, Deeper penetration • eg. >20 kW SM CW laser for high speed fine cutting or deep welding. • => higher throughput, quality, application flexibility (novel & improving traditional) Coherent Beam Combining (CBC) at different wavelengths • Ability of HP SM in different Wavelengths to match the work material • eg. 500 watt SM CW “green” laser for copper welding of electric interconnects • => better process quality, throughput, novel process with new materials OPA CBC - High power Single Mode with Dynamic beam • Beam steering, focusing & shaping in MHz regime • eg. 5kW SM OPA CW with fast beam steering and dynamic focusing • => high speed additive manufacturing, improved cutting and welding
- 6. www.civan.co.il Remote Operation • RemoteProcessing Leads to increased versatility and speed • Remote operation is highly relevant for the auto and additive manufacturing industries
