BPR
IPOptica's BPR line of BBO based Pockels Cells has been specifically designed to satisfy the demands of high power damage threshold, low piezo effect, low insertion loss and other benefits. Operated by lPOptica's fast switching electronic drivers, BPR devices deliver top-industrial laser reliability and performance for high power and high pulse repetition rate lasers at the wavelengths from 19Onm to over 2.2um.
Our BPR devices rely on the Pockels effect including single-crystal and double-crystal design to convince practical usage in Q-switching, pulse picking, cavity dumping, and other applications. To compensate the high voltage request especially on big aperture ones({>}3.6mm) for the low electro-optical coefficient of BBO, our double crystals design half the switching voltage,to benefit on expediting the switching times and repetition rate.
Great suppression of Piezo effects
High Transmission Rate and low insertion loss
Broadband working wavelength (190nm~2.2um)
High damage threshold
Reliable structure up to 100W power and HVpulse re petition rate up to 2MHz.
Low thermal lensing effect and thermal depolarization phenomena
Suited for high repetition rates Q-Switching
Pulses coupling application of Picosecond and femtosecond regenerative amplifier
Pulse picking and optical switch
