About this file
This document outlines the technical specifications for an ultrafast pump-probe laser system procurement by the Department of the Navy. The system requires two Ti:Sapphire ultrafast oscillators with center wavelengths around 800nm, tunable ranges from 750-850nm, pulse widths less than 30fs, average powers over 550mW, and repetition rates of 80MHz or greater. Additional components include a 5W pump laser, prism-based pulse width and wavelength control software, a repetition rate stabilization electronics package to synchronize the pump laser to the probe laser between 1-20kHz, diagnostics for one laser, and a control computer. The contractor must provide a one year warranty on the system and conduct on-site installation and training.
The related federal contract opportunity is a solicitation from the Department of the Navy Secretary of the Navy Office of Naval Research seeking proposals for the ultrafast pump-probe laser system defined in the technical specifications document.

Ultrafast pump-probe laser system
Description: Code 6883 has a requirement for a commercially available system that consists of two ultrafast lasers with an electronics package for synchronization, in order to preform ultrafast spectroscopy of thin film samples. The synchronization timing will be performed using a technique known as asynchronous optical sampling (or equivalent technology), where the repetition rate of the pump laser will be dynamically tuned to match that of the probe laser with a frequency offset that is adjustable in the range 1-20 kHz or wider. The system will be fully integrated with the pump laser and both ultrafast oscillators mounted on a common breadboard.
Specific Requirements:
• Ti:Sapphire ultrafast lasers: Fully engineered and integrated oscillator with water-cooled and temperature controlled breadboard and Ti:Sapphire crystal.
• Center Wavelength: ~ 800 nm
• Tunable wavelength range of approximately: 750 - 850 nm
• Pulse width: < 30 fs (fixed center wavelength at 800nm).
• Average power: > 550 mW
• Repetition Rate: 80 MHz or greater (up to 1 GHz acceptable)
• Maximum bandwidth: > 70 nm FWHM; Minimum bandwidth: < 25 nm FWHM.
• Power stability: < 1 % RMS over 8 hours after warm-up and +/- 0.5 C room temperature stability.
• Pump laser: integrated 5W laser with chiller.
• Software control of pulse width and center wavelength.
• Both lasers will be mechanically built onto a common breadboard
• The repetition rate of the pump laser will be dynamically tuned to match that of the probe laser with a frequency offset that is adjustable in the range of 1-20 kHz or wider
• Repetition Rate Stabilization electronics will provide a choice of synchronizing the repetition rate of the pump laser to another laser source (probe oscillator) or an external signal generator. The locking electronics should reduce timing jitter to < 150 fs
• Diagnostics electronics for at least one laser: includes a spectrometer, large-area photodiode power monitor, pickoff window and mounts for monitoring the output of oscillator.
Electronics Package should include:
– Oscillator Controller box housing a stepper motor controller and pulse-train RF amplification circuitry.
– Stepper motors and adapters for prism translation stages.
– Mounted photodiode compatible with oscillator controller for monitoring oscillator pulse-train.
– A system for generating trigger pulses that mark pump-probe temporal coincidence, based on a two-photon detector.
– Laptop control computer with pre-installed software and drivers for controlling prism motors.
• The system can be readily moved to a new optical table or optical setup
• The contractor must provide a warranty on the entire system for at least 1 year
• The contractor must provide on-site installation and training
