Paper Abstract

According to the requirement of high power laser beams and beam focus diagnostic instrument for measuring laser transverse intensity distribution, a new method of CO2 laser rapid detecting by pyroelectric detector is given. The rapid response of photoelectric transformation with large enough gain is obtained. The response time is shorter than an order of magnitude comparing with common method. The detector can operate in normal room temperature, and need no cooling set. The photoelectric transformation system satisfies the measurement requirement of high power laser density cross-section distribution. The method can be employed for application concerning with rapid response of pyroelectric detector.
