The invention generally relates to systems and methods for controlling molecules. In certain aspects, the invention provides a system for controlling molecules, the system comprising: a first light source; a second light source; an acousto-optic modulator (AOM) coupled to the second light source; and control circuitry. In certain embodiments, the control circuitry may be configured to: receive a signal from the first light source that is interrogating a location in a sample that may contain a target molecule; compare the signal received from the first light source to a preset signal; and in the event that the signal received from the first light source meets or exceeds the preset signal, then the target molecule is present at the location in the sample and the control circuitry causes the AOM to activate the second light source to transmit light onto the location in the sample that contains the target molecule.

A high-frequency (HF) driver circuit for an acousto-optical component includes an HF power amplifier connected to a voltage regulator for supply with a supply voltage and a bias voltage generator connected to an input of the HF power amplifier via a switch. The HF driver circuit can include a measurement device configured to measure a temperature of the HF power amplifier and a compensation device configured to control the bias voltage generator according to the temperature. The bias voltage generator is configured to provide a bias voltage to the HF power amplifier. By switching in the bias voltage, the HF power amplifier can be adjusted to a low quiescent current. By switching off the bias voltage, the HF power amplifier can be very rapidly and effectively blocked. As a result, very rapid switching-on and switching-off times, e.g., in a range of 10 to 50 ns, can be achieved.

This present disclosure describes a method, a device, and a system for performing a pulse shaping method that accurately converts short laser pulses into arbitrarily programmable optical waveforms with much longer duration. The optical pulse shaping method is based on multi-frequency acoustic-optic modulation and retro-diffraction based multiple optical delay line generation. Regarding the optical pulse shaping method, precise high-speed programming control on amplitudes, phases, and delays of a picosecond ultrashort sub-pulse sequence is implemented, to obtain an arbitrary waveform optical pulse with a near-THz bandwidth and a coherence time up to nanoseconds, for applications in quantum control of atomic/molecular optical transition.
