Specifications:
The document provides specifications for various energy sensors, including PES and HR models. Each model is characterized by its sensitivity, repetition rate, dimensions, and connector type. Sensitivity is measured in V/J at different load resistances (1 MΩ, 100 kΩ, 50 kΩ), and repetition rates vary accordingly. Dimensions are given in mm², and connector types are specified as M3 or M4.

Procedures:
The sensors are designed for energy monitoring of high repetition rate lasers. They are co-axially built, offering high sensitivity across a wide spectral range (190 nm to 25 µm). The maximum repetition rate is influenced by the sensor diameter and load resistor, with values up to 3000 pulses per second (pps) possible.

Norms and Recommendations:
The sensors can handle a maximum energy density of 150 mJ/cm², a maximum power density of 150 mW/cm², and a maximum average power density of 8 MW/cm² for a 10 ns pulse. They operate within a temperature range of 0 to 40°C and have an accuracy of ±5%.

Data Summary:
The document includes sample output signals for different sensors (HR 11, PEM 11, HR 4) with specified divisions and load resistors. These samples illustrate the performance characteristics under various conditions.
