BPU
Our BPU devices rely on the Pockels effect applied cooling system and a variety of new materials to utmost suppressing heating especially for the request of High power Ultra-fast lasers. To compensate the high voltage request for the low electro-optical coefficient of BBO, the double crystal design half the switching voltage, to benefit on expediting the switching times and repetition rate.
Large aperture BBO based Pockels Cells with water-cooling applied to utmost suppress heating
Great suppression of Piezo effects
High Transmission Rate and low insertion loss
High damage threshold
Reliable structure has been iested up to 700W power wlth pulse repetitlon rate up to 500kHz.
Low thermal lensing effect and thermal depolarization phenomena
Pulses coupling application of Picosecond and femtosecond regenerative amplifier
Pulse picking and optical switch
