Description

The Lawrence Livermore National Laboratory (LLNL) is seeking sources for an Optical Comb Generator (OCG) for the National Ignition Facility (NIF) Project. The NIF Project is funded by the Department of Energy (DoE) and is being constructed at LLNL. The NIF is an inertial confinement fusion research facility that will contain 192 independent laser beams converging in a fusion-target chamber. The OCG will be utilized as part of the NIF diagnostic equipment and will operate at a fixed wavelength between 500 and 700 nanometers with shorter wavelength being preferable. The OCG will provide a time reference signal on high-speed streak cameras operating from 2.5 to 1000 nanoseconds full-scale sweep. Previous OCGs have employed directly modulated laser diodes operating at 820 nanometers. These OCGs work well for streak cameras having an "S1" photocathode response but are too long a wavelength for cameras with an "S20" photocathode response. The OCG will produce an optical pulse train with the following fixed frequencies: 10 MHz, 20 MHz, 40 MHz, 100 MHz, 200 MHz, 400 MHz, 1 GHz, 2 GHz, and 4 GHz. The frequency will be selected by a digital interface and a local select control. Well-defined pulses with a pulse width less than 25% of the period for each frequency are preferable to purely sinusoidal pulses. Mach-Zender type modulators provide a suitable pulse shape. The pulse train will be gated by an externally triggered macro-pulse adjustable from 1 to 10 microseconds. The pulse rate of this macro-pulse will be 10 Hz or less. The average optical power will therefore be very low but peak power from 2 to 5 microwatt in each pulse is required. The OCG design should be compact (12 inches x 4 inches x 4 inches or smaller) and robust so that alignment or adjustment are rarely needed. Technical questions may be addressed to Mark Rhodes via e-mail at plasma99@llnl.gov.
