The Power Supply/Timing Generator (PS/TG) is housed in a standard 19"wide (3U size) rack mountable configuration. New in 2019 with 6cm depth reduction. Voltage is adjustable by two methods, via a manual knob or voltage control by applying a 0 - 5 volt control voltage. The driver can operate at the HWV (half wave voltage) or less without loss of efficiency or increased of rise or fall times. The timing generator circuits provide pulsing of the cell up to 5kHz synchronized with up to a 100Mhz pulsed laser.
The Optical Head Assembly OHA contains the HV Pulse Switch Modules. These are designed for voltages suitable for up to ½ wave operation of KD*P Pockels cells at 1064nm. Pockels cell voltage is linear with wavelength, and voltage is adjusted for the specific cell and wavelength. The ON and OFF switches incorporates reliable MOSFET technology. The 5046ER series Systems provide rise and fall times as fast as 3ns. The 5046 series systems can be utilized for both intracavity and extracavity applications.
The 5046 series driver's performance limits were designed based on the operating limits of popular DKDP pockels cells. Piezo response of DKDP crystal defines 5kHz and pulse width 1 us as the upper practical limits. The specific Pockels cell may define optimal OPTICAL performance criteria that are lower than the driver's maximum ratings.
Optical switching is accomplished with a voltage potential applied across a Pockels cell. Pockels cells switched at HWV rotate the incoming plane of polarization of the laser beam 90 degrees in response to the electrical voltage. This fast ON and OFF switching of the Pockels cell all occurs as fast as 8ns, the gated pulse width and can be adjusted up to 1us pulse width. Applications desiring circular polarization are switched at QWV quarter wave voltage.
When picking pulses from a 80 MHz laser the pulse width is typically set to pick single pulses and PW adjust control is set to ~ 10-15ns at some rate up to 5kHz. As the HV PW is increased the driver will pick a pulse train. DKDP Pockels cells operate best when operated with short HV pulses cell ON time of ~200ns or less. Operating with longer HV pulses results in piezo ringing and cell leakage resulting in lower extinction.
Pockels cell model Q1059PSG with 10mm aperture is standard with the system. Common upgrades include 12mm and 16mm aperture DKDP cells. Our full line of Pockels cells are available to optimize the 5046ER system for your application including Series 1147 RTP and Series 1150 BBO cells. These cover an optical spectrum of 240 nm to 2500nm. FastPulse DKDP Pockels cells include models from our Q1059, CF1043, CF1042 and 1144 product lines covering the UV to 1064nm and up to 30mm apertures. FastPulse Technology is a vertically integrated company. Our DKDP is grown in house and fabricated into Pockels then installed and tested with the driver.
Pockels cells are mounted, on a tilt gimbal, within the OHA. NEW: A vertical oriented OHA model 5046EV now allows a smaller foot print configuration. This is an option and must be specified at time of order.
Driver Product lines with higher repetition rates up to 100kHz are offered with our 5100ERW series drivers. The series 8025RS Pulsers provide long pulse widths (50ns to 10's seconds) and high duty cycle. These drivers required either RTP (series 1147) or BBO (series 1150) Pockels cell for high pulse rate and long pulse width applications. These crystals have greatly reduced or no piezo ringing. All drivers include interconnecting cables, along with a User's Guide Manual (see website) with illustrations on setup and configurations.
