Optical Power & Energy Measurement

Optosigma Optical Power and Energy Measurement systems provide traceable measurement of laser output power and pulse energy across a wide range of wavelengths and power levels.

Photodiode power sensors:
– Silicon (Si) photodiodes: 190 nm to 1100 nm; power range 1 nW to 200 mW
– Germanium (Ge) photodiodes: 700 nm to 1800 nm; suited for telecom and NIR lasers
– InGaAs photodiodes: 800 nm to 1700 nm; low noise for CW single-mode fiber output measurement
– Calibrated with NIST-traceable standards; uncertainty below 3%

Thermal power heads:
– Broadband absorption coating: 190 nm to 20 um; flat spectral response
– Power ranges: 30 mW to 30 W per head; higher power with attenuator
– Response time: 1 to 5 seconds to 95% reading (thermal equilibrium)
– Used when absolute accuracy is required or photodiode saturation is a risk

Pyroelectric energy sensors:
– For pulsed lasers: Nd:YAG, CO2, excimer, fs/ps laser systems
– Energy range: 1 uJ to 2 J per pulse
– Repetition rate: up to 25 kHz
– Wavelength: 190 nm to 20 um with appropriate window

Power meters (displays and controllers):
– Digital display with USB and RS-232 output
– Auto-range, min/max, statistics, data logging
– Compatible with all Optosigma power and energy heads
