The Pacific Northwest National Laboratory, herein known as PNNL, operated by Battelle Memorial Institute, under Contract No. DE-AC05-76RLO 1830, with the U.S. Department of Energy, herewith solicits your quote for a tunable high-power femtosecond Ti:Sapphire oscillator based laser system for surface spectroscopy, including pump laser and related options, to conduct ultra sensitive surface nonlinear spectroscopy measurement.

The equipment shall meet the following requirements:

1. The pump lasers should be a diode-pumped solid-state lasers.

2. The laser system needs to provide high average power ( > 3.5 Watt @ 800nm) with < 150 femtosecond pulses over the entire 700-1000 nm wavelength range, with a single optics set. The laser system should have the option to be operate ~1 to ~10ps pulse durations.

3. The high power Ti:Sapphire oscillator laser shall be used to pump OPO/SHG/THG devices to provide gap-free tunable laser output from ~300 to > 2600nm.

4. The OPO output can be used to pump a DFG device with the OPO output to achieve 2.6 to 15micron (5 mW @ 5 microns) tunability in the IR is highly desired. (This requirement is optional but highly desired.)

5. This high power system needs to have the potential to be synchronized to a ~ 50-100ps Ti:Sapphire oscillator laser. The jitter should be < 0.5ps. (The ps laser is not necessary from the same vender as the fs laser system.)

6. Ultrafast laser optical components and opto-mechanical devices, delay lines with various need. (Not necessarily from the same vender as the laser system.)

7. One high resolution spectrograph with at least 0.2cm-1 resolution in the spectral range 250nm-1000nm with ultrasensitive CCD or EMCCD; A second moderate resolution spectrograph with CCD or EMCCD will also be needed. (Not necessarily from the same vender as the laser system.)

8. The tunable high-power femtosecond Ti:Sapphire laser system shall satisfy the following primary operating performance criteria.

9. Stability test data for the fs laser system under humidity/temperature fluctuation need to be provided.

10. On-site installation and training shall be included with the purchase, to commence within fourteen (14) days of delivery.

11. Instrumentation shall have a two year onsite parts, travel and labor warranty that includes a minimum of one on-site preventative maintenance service call per year. The warranty shall commence after system acceptance.
