| Abstract: | The photothermal detuning technique is a novel photothermal technique, utilizing the spectral shift of optical coatings caused by absorption-induced temperature rise to measure the absorption of the optical coatings.Experiments are conducted with a highly reflective coating deposited on BK7 glass substrate.The pump laser is a CW laser.The transmitted and reflected configurations are studied.The influence from the incident angle of the pump beam is analyzed.The results show that the transmitted signal and th... |
