Picosecond Pulsed Diode Laser Driver - PDL 800-B

The PDL 800-B is a stand-alone driver for the picosecond pulsed laser diode heads from 375 to 1550 nm (LDH Series, LDH-P-FA-530) as well as for the sub-nanosecond pulsed LEDs from 255 to 600 nm (PLS Series). The laser heads can emit light pulses as short as 70 ps FWHM (50 ps on selection) at repetition rates from single shot up to 80 MHz with peak powers up to 1 Watt (depending on wavelength). The PDL 800-B features easy-to-use controls for repetition frequency and laser pulse energy. Wavelengths can be changed quickly by simply plugging in a different laser or LED head.

User-selectable repetition frequencies of 40, 20, 10, 5 and 2.5 MHz are derived from the internal crystal controlled oscillator that generates a low jitter base frequency of 40 MHz (64 or 80 MHz are available for red diode laser heads upon request). The laser pulses can also be triggered by an external trigger input so that the PDL 800-B can be synchronized with other instruments over the full frequency range. A sync output allows the PDL 800-B to trigger other components such as TCSPC electronics. An additional gating option permits to disable the laser output through an external TTL-signal.
