Quanta-Ray® Lab Series

UNSURPASSED PERFORMANCE, RELIABILITY, AND QUALITY

  • Repetition rates from 1 to 100 Hz with energies in excess of 1 J per pulse
  • Gold elliptical pump chambers
  • Sealed beam paths
  • High-quality, high-damage-threshold optics from Spectra-Physics’
         dedicated in-house coating lab

Spectra-Physics Quanta-Ray high-pulse energy Nd:YAG lasers are recognized world wide for their unsurpassed performance, reliability and quality. They incorporate pioneering technologies such as dual-rod oscillators, gold-coated elliptical pump chambers, internal sealed beam paths, and high-damage-threshold optics from Spectra-Physics’ advanced coatings lab—all combine to create the best beam quality and highest energies in the industry.

The heart of the Quanta-Ray laser is its unique pump chamber. The chamber strikes the perfect balance between efficiency and beam mode quality by employing elliptical goldcoated reflectors to couple the lamps into the Nd:YAG rod. The gold surfaces provide high reflectivity at pump wavelengths while attenuating UV wavelengths. Proprietary diffusion techniques ensure uniform illumination of the Nd:YAG rod.

Quanta-Ray lasers are also the only lasers on the market to feature completely sealed internal beam paths through the use of nitrogen-purged beam tubes. Sealed beam paths greatly extend the longevity of optical coatings by shielding all optical components from harmful contaminants in even the harshest of environments. Spectra-Physics uses only Sol-Gel coated pockels cells. This coating greatly enhances the lifetime of the cells and improves the performance of the laser system. BBO FHGs give highest energies, best beam quality and highest damage thresholds. These features lead to the best “bumper-to-bumper” one-year warranty on all optics, mechanics and electronics available from a pulsed YAG supplier.

Newly incorporated modern digital signal processing (DSP) electronics in all Quanta-Ray Nd:YAG lasers provide a modern control system for the user. Direct digital interface and Graphical User Interface (GUI) enables intuitive control of the system and simplified integration with complex systems.

The Quanta-Ray Lab series represent the intermediate range of oscillator-only lasers with output energies up to 1 J at 1064 nm. The Lab laser stands above its competitors because of its dual Nd:YAG rod and dual pump chamber oscillator configuration. This proprietary design provides intra-oscillator compensation for thermally-induced birefringence in the Nd:YAG rod, greatly reducing beam depolarization. This results in higher repetition rates, higher average powers and superior output beam quality than any other oscillator-only Nd:YAG laser on the market.

1. All specifications, unless otherwise stated, are for Q-switched 1064 nm operation and are subject to change without notice.
2. Harmonic energies are specified after separation using dichroic mirror pairs. It is also assumed that polarization of measured harmonic is in vertical polarization,
    making an “S” polarized reflection from dichroics. 532 nm energies are specified using Type II SHG. 355 nm energies are specified using Type II doubler.
    Using a Type I doubler in tripling process will result in a 10% increase in published 355 nm specification except for the following models: Lab-130-10, Lab-190-10.
3. Addition of LBP option for pumping Scan Series OPOs can result in a 5% loss of 355 nm energy. EEO - high UV output option designed for OPO pumping,
    includes injection seeder, harmonic generator, 355 nm dichroic separators, and beam dump.
4. The Lab-190-10 is configured on a Quanta-Ray Pro platform. This allows for BeamLok in this model. For laser head size,
    please refer to Quanta-Ray Pro specifications.
5. Normal full width half maximum (FWHM) pulse width 8-10 ns for all Lab series lasers except Lab 130-10 and Lab 190-10 versions, which is 9-12 ns.
    The optional short pulse mode reduces the 1064 nm pulse width to approximately 2.5 ns and reduces the energy by approximately 10%.
    (Short pulse mode available on seeded versions on special request only).
6. Pulse-to-pulse stability for >99% of pulses, measured over a 1 hour period.
7. Over 8 hour period with temperature variations of <±3°C.
8. Near field spatial profiles measured <1 m from laser using commercially available beam diagnostic system. 70% refers to correlation between actual
    beam profile and least squares best fit Gaussian profile. Far field profiles are measured at focal plane of a 2 m focal length lens and measured between
     FWHM points. Specifications based on 10 Hz lasers. Fit to flat-top central 80% of beam near field.
9. Enhanced spatial mode options can be tailored to meet your application needs. To obtain >85% Gaussian fits, energy can be reduced by 50%.
    Contact Spectra-Physics to establish specifications.
10. Refers to maximum deviation from best fit Gaussian profile measured in near field (1 m) between FWHM points.
11. Actual beam diameter will vary depending on laser configuration.
12. Long term average pointing drift after warm up, over 8 hours ±-3°C. Shot-to-shot pointing stability <±25 μrad. Angle measured is polar angle.
13. Full angle measured at FWHM points.
14. IR energy within 10% of specified value.
15. Insertion losses for systems using model 6350 injection seeder are <15% at 1064 nm, 532 nm, and 266 nm.
16. RMS jitter from Q-switched sync pulse at 10 Hz. Jitter is ≤1 ns RMS when using model 6350 injection seeder at 10 Hz and ≤1.5 ns at 30 Hz.
17. Lab 130-10 and Lab 150-10 units are air cooled as standard. Water-cooled versions of Lab 130-10 and Lab 150-10 require PS101(3.8 liters/min
      or 1.0 US gal/min). All seeded lasers must be water cooled.
18. Minimum pressure 40 psi. maximum pressure 60 psi.
19. Input transformer has taps at 190, 200, 210, 220, 230, 240, 250, and 260 V. Once tap is chosen, actual input voltage differing by more than ±10%
      may affect operation of laser.
20. Measured on request.
21. Max current draw of laser.
