|
Laser damage testing across CW (continuous wave), NS (nanosecond), PS (picosecond), and FS (femtosecond) pulse regimes, spanning UV to IR spectral ranges in air and vacuum environments. Services include ultra-low-loss absorption measurements (down to 1 ppm), optics lifetime estimation, and tailored solutions for high-power optics manufacturers, distributors, and end-users.

LASER-INDUCED DAMAGE THRESHOLD (LIDT) TESTING Laser Damage Testing is available in CW (continuous wave) – Nanosecond – Picosecond – Femtosecond pulse regimes, from IR to UV spectral range in Air or Vacuum. LIDARIS offers standard (ISO-21254) tests such as S-on-1, 1-on-1, and ISO Certification/Acceptance. Additionally, functional LIDT tests such as R-on-1 and raster scan or custom LIDT testing procedures are available. |

ABSORPTION TESTING AT PPM LEVEL WITH PCI Photothermal Common-path Interferometry (PCI) is probably the most popular option for the characterization of low-loss optical absorptance of dielectric coatings at ppm level. It is a spatially resolved pump-probe technique. The standard measurement pack includes three test procedures: Transverse scan (T-Scan); longitudinal scan (L-scan) through the depth of the transparent sample and Time-scan – absorption is monitored at one site for 10 minutes. Testing is available from IR to UV spectral range. |

OPTICS LIFETIME TEST Typical LIDT testing usually is limited to irradiations lasting only a few seconds or minutes. To match real-life application requirements (such as years of uninterrupted laser operation) much longer testing is needed. At LIDARIS we perform extended testing based on the S-on-1 test approach and employ novel statistical analysis techniques to estimate the lifetime of optical components by characterization and prediction of optical fatigue behavior. |

TEST BUNDLES AND PACKAGES FOR OTPICS CHARACTERIZATION Sometimes more than one test is necessary in order to characterize laser optics in terms of laser-induced damage performance. We suggest a unique opportunity to order test packages, which address various practical needs. LIDT tests can be also combined with low-loss absorptance (PCI) tests. |
