Abstract : Progress to date is summarized as follows: 1. Experimental confirmation has been made of the pulse formation mechanism in a laser modelocked by a slow saturable absorber as proposed by New and Haus. 2. We have shown analytically and experimentally that the degree of coherence is the same in a diode laser whether modelocked or singlemode at the same power. 3. The continuously operating phosphate Nd:glass laser has been modelocked for the first time ever to generate 7 ps pulses. We have also successfully amplified these pulses to J/pulse at 500 Hz rate. Keywords: Neodymium lasers; Pulsed lasers; Photoconductivity; Optoelectronic devices; Nitrogen laser; Low energy lasers.
