Laser Power Meter - Pyroelectric Smart Heads

Product catalog summary

Overview: The document outlines the specifications and features of pyroelectric, photodiode, and RP (Repetitive Pulse) heads used for precise energy measurements in pulsed lasers. These devices are designed for high accuracy and versatility.

Pyroelectric and Photodiode Heads: These heads employ patented technology for accurate measurements under various conditions. Key features include:

Accuracy: Independent of pulse rate, duration, or history, with built-in wavelength correction.
Performance: Capable of measuring pulse rates up to 20,000Hz and energy as low as 10pJ, with a high damage threshold and removable diffusers for high-energy lasers.
Versatility: Suitable for both long and short pulses, compatible with various displays, and capable of high-frequency data storage and transmission.

RP Heads: These heads integrate thermal and photodiode measurements for precise energy per pulse readings, providing comprehensive laser performance data. They can store up to 50,000 data points and display pulse shapes with high resolution.

Specific Models:

PD10: Measures pulse energy from 1nJ to 20µJ at up to 10,000Hz, ideal for low energies and high repetition rates.
PD10-pJ: Measures extremely low energies from 10pJ to 200nJ, with similar frequency capabilities as the PD10.
PE9/PE9-F: Designed for low energy measurements, with the PE9-F supporting higher repetition rates up to 20KHz.
PE10/PE10BB: Suitable for low energy lasers with a broad spectral range, offering different absorber options.
PE25/PE25BB: General use for medium aperture pulsed lasers, offering high sensitivity and a spectrally flat option.
PE50/PE50BB: Designed for large aperture pulsed lasers, with options for high sensitivity and long pulse measurements.
PE25BB-DIF/PE25-DIF: Features a diffuser for high damage threshold, suitable for high energy YAG lasers.
PE50BB-DIF/PE50DIF-ER: Offers removable diffusers for high energy and high repetition rate lasers, including Erbium lasers.
PE50-DIF-U: Specifically for Q-switched lasers in the UV range, with high damage threshold and repetition rate capabilities.
