Mode locking of a Nd:glass with LiF:F - 2
Abstract
The passive mode-locking characteristics of LiF:F2(-) as a storable absorber were examined in a Nd:phosphate glass laser. The 0.53 micron laser 1 nsec pulses were monitored in both conventional and Q-switched modes. The pulse trains were recorded by a storage oscilloscope and a streak camera. The mode-locked output pulses had a FWHM pulse width under 50 psec. The hysteretic delays in the F2(-) recovery times caused the occurrences of multiple pulsing of mode-locked pulses during each burst packet, although a 100 percent modulation depth was achieved. The possibility of adding other color centers to the LeF:F2(-) crystals to improve the performance of ultrashort lasers in the IR region is indicated.
