9 General specification Material of the sensitive elementZnSe Sensitivity, V/W10 -5 ÷10 -2 Spectral Range, μm2÷12 Diameter of the active area, mm10÷20 Transmission factor>0.95

10 Areas of application Sensitive element of the control-measuring instruments for industrial lasers; Transmitting optical element for feedback systems; Multifunctional element for laser beam focusing and simultaneous measuring of beam's intensity; Laser exit window capable of measuring laser beam intensity.

11 Innovative Aspects and Main Advantages The distinguishing feature of our transmission-type sensor is the possibility to read out desirable data at any point of the optical system without placement of any extra optical elements. Specific features of the tertiary pyroelectric effect gives advantage to offered sensor by setting the upper limit of the dynamic range up to several kW/cm 2, which is determined by the crystal's resistance to laser radiation in the vicinity of the transparency maximum.

12 Our proposals The sensor is developed to read both temporal and energy characteristics of radiation beams from the high power industrial lasers operating in a frequency- pulsed mode. Fabrication one sample 1000$
