<p>An eye-safe light source for the efficient excitation of anti-Stokes materials in up-converting mode comprises lasers operated in pulsed mode, with the pulses having a relatively high peak power (PP) while choosing pulse duration and pulse repetition frequency such as to yield a relatively small mean power (MP) of less than 5 mW, preferably less than 1 mW, more preferably equal or less than 0,5 mW.</p> |
