Quanta-Ray® Nd:YAG lasers are recognized world wide for their unsurpassed performance, reliability and quality. The Quanta-Ray INDI Series are oscillator-only YAG lasers with a single rod and pump chamber configuration. Our proprietary resonator design combined with Quanta-Ray’s unique gold-coated elliptical pump chamber produces an output beam quality that is superior to other low energy pulsed lasers available on the market.
Newly incorporated modern digital signal processing (DSP) electronics into all Quanta-Ray YAG lasers provide a number of advantages for users.
|
A direct digital interface and GUI enhances the reliability and convenience of using Quanta-Ray INDI, maximizing the time spent doing experiments.- Variable repetition rates are now possible with digital control. This digital control lets the user set the rep rate to integer-fractions of the lamp pulse frequency. Thus, the thermal steady-state in the resonator is maintained by a constant flash lamp frequency, but the rep rate of the light output can be varied.
|
The traditional features and advantages that have made Quanta-Ray the world's leading pulsed Nd:YAG laser are still integral to our design philosophy for laser quality. These features include gold-coated elliptical pump chambers, internal sealed beam path and high-damage-threshold optics from Spectra-Physics’ advanced coatings lab. |

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. 532 nm energies are specified using type II second harmonic generation (SHG). 355 nm energies are specified using type II SHG. A 10% increase in 355 nm energies can be specified when type I SHG is used.
3. High UV output option designed for OPO pumping, including 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. FWHM for Pro series lasers is 10-12 ns except for Pro 270-10, Pro 290-10, and Pro 350-10 versions which is 8-10 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 an 8 hour period with temperature variations of <±3°C.
8. Near field spatial profiles measured 1 m from laser using a commercially available beam diagnostic system. 70% refers to the correlation between the actual beam profile and the least squares best fit Gaussian profile. Far field profiles are measured at the focal plane of a 2 m focal length lens and measured between FWHM points. Specifications based on 10 Hz lasers.
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 the maximum deviation from the best fit Gaussian profile measured in the near field (1 m) between the 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 the 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 the Model 6350 injection seeder at 10 Hz, ≤1.5 ns at 30 Hz, and ≤2 ns at 50 Hz. INDI cannot be seeded.
17. Both INDI, Lab 130-10 and Lab 150-10 units are air cooled as standard. Water-cooled versions of INDI require WAT 50 (3.8 liters/min or 1 US gal/min). 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.
