Design of High Power VECSEL

• Approach
• Large number of QWs with Resonant Periodic Gain
• Active region close to effective heat sink
• Thermal management by substrate removal, heat
  spreader approach

• InGaAs/GaAs /GaAsP strained compensated MQW
• Resonant periodic gain (RPG) MQW
• DBR on Chip
• Barrier Optical Pumping
