Abstract: PROBLEM TO BE SOLVED: To provide a highly accurate method for evaluating the laser durability of an optical material and an optical thin film and its device. SOLUTION: A computer 92 controls conditions such is the pulse width and irradiation frequency of laser light emitted from the light source 1 by controlling the light source 1. Such laser light is polarized to be incident on a sample SA as measuring light L4. In addition, the computer 92 detects measured values by a reference light sensor 8 via an oscilloscope 91 and computes the laser light intensity of the measuring light L4 at the surface of the sample SA on the basis of the measured values. In addition, the computer 92 detects measured values by a photoacoustic detecting element 6 via the oscilloscope 91 and observes the fluctuations of acoustic signals which occur from the sample SA, i.e., changes and fluctuations in the amount of absorbed light due to the irradiation of the measuring light L4 on the basis of the measured values.  By this, it is possible to evaluate the alteration, degradation, and destruction of an optical material and optical thin film of the sample SA in more detail with high accuracy.
