Presented at ILSC 2009

Although the total on time pulse (TOTP) method has been successfully used to compute the maximum permissible exposure for repeated exposure to laser energy, some modification to the method must be made when the pulse duration is short and the pulse energies vary from pulse to pulse. Alternative methods to TOTP are presented for pulses of varying energy as well as a modification to the TOTP method that will provide a more accurate assessment of the hazards.
