Lambda Photometrics Announces Arrival of Volume Absorber Suitable for Measuring Average Power of Lasers

Lambda Photometrics is pleased to announce the arrival of a brand new Volume Absorber suitable for measuring the Average Power of lasers with higher peak powers than ever before. With a higher damage threshold and improved durability, the UP19K-VR series detectors are an excellent replacement for the UP19K-VM/VH series detectors.

The highlights of this new detector offered in the UP19K housing are:

• Available in 15W stand alone and 30W heatsink versions
• Maximum Energy density: 6 J/cm2 (1064nm, 7ns, 10Hz)
• Maximum Peak Power Density: 860 MW/cm2 (1064nm, 7ns, 10Hz)
• Maximum Average Power Density: 700W/cm2
• Excellent measurement accuracy (calibration uncertainty: +/- 2.5%)
• A low noise level (Noise Equivalent Power level: 2.5mW);
• The improved 700W/cm2 specification has a direct impact on the durability of absorber itself. Typical glass absorbers will chip with repetitive pulses. The 230% increase in maximum Average Power density will prevent this type of degradation.

The new VR detector is suitable for use in conjunction with high energy Q-switched Nd:YAG lasers such as:

• Quantel Brilliant EaZy
• Quantel Brilliant
• Quantel Brilliant B
• Quantel USA CFR 400
