EOQ-KD*P Optoelectronics & Engineering Services Pockels cell KD*P APPLICATIONS HIGHLIGHTS Finest strain-free KD*P High contrast ratio • OEM laser systems High damage threshold • Versatile R&D laser platforms Low 1/2 wave voltage Space efficient Ideal for compact lasers Ceramic apertures Clean and highly damage-resistant High contrast ratio Exceptional hold-off Quick electrical connectors Efficient/reliable installation Ultra-flat crystals Excellent beam propagation APPLICATION A Pockels cell alters the polarization state of light passing through it when an applied voltage induces birefringence changes in an electro-optic crystal such as KD*P. When used in conjunction with polarizers, these cells can function as optical switches, or laser Q-switches. EOQ-KDPdejh.doc PRINCIPLE OF OPERATION Our KD*P Q-switch employs the finest strain-free, highly deuterated KD*P available. Based on our advanced crystal fabrication and coating technology, we can offer EO Q-switches for a variety of laser wavelengths exhibiting high transmission (T>97%), high damage threshold (>500W/cm2 )and high extinction ratio (>2000:1).
