J-50MB-YAG Pyroelectric Energy Probe Compatible with FieldMaxII-TOP:

Pulse energy measurement range 1.5mJ—3J, noise equivalent energy <50μJ
Maximum average power measurable 20W, maximum repetition frequency 50Hz
Response wavelength range 0.266—2.1μm, effective measurement diameter 35mm
Maximum pulse width 340μs, maximum energy density 14J/cm² (at 1064nm, 10ns pulse)

The J-50MB-YAG energy sensor is specifically designed for high-energy and high-peak-power lasers operating at relatively low repetition rates, such as Nd:YAG, ruby, Ho:YAG, and erbium-based lasers. The J-50MB-YAG can be used for beams up to 35mm in diameter, operating at wavelengths of 1064 nm, 532 nm, 355 nm, and 266 nm, without the need to replace diffusers or self-calibrate the sensor.

This sensor is terminated in a SmartProbe DB25 cable and is directly compatible with FieldMaxII TOP, FieldMaxII-P, LabMax TOP, and LabMax Pro SSIM meters.

Available in USB direct (PN 1191437) and RS232 direct (PN 1191430) models.

A large heat sink (PN 1123432) can be used to extend the energy and repetition rate capabilities of the EnergyMax sensor by increasing average power capacity.
