Efficiency of resonance pumping and optical gain in a Nd-doped phosphate glass excited by diode arrays

The gain {approx}3.5x10{sup -3} cm{sup -1} is obtained in the repetitively pulsed regime upon pumping a Nd-doped phosphate glass into the {sup 4}I{sub 9/2}-{sup 4}F{sub 3/2} absorption band by diode arrays at 874 nm. The pump efficiency for a sample of volume 6.7 cm{sup 3} exceeded 0.5 and was limit...

Summary:The gain {approx}3.5x10{sup -3} cm{sup -1} is obtained in the repetitively pulsed regime upon pumping a Nd-doped phosphate glass into the {sup 4}I{sub 9/2}-{sup 4}F{sub 3/2} absorption band by diode arrays at 874 nm. The pump efficiency for a sample of volume 6.7 cm{sup 3} exceeded 0.5 and was limited only by the geometrical factor and the excited-state lifetime of the Nd{sup 3+} ion. (lasers and amplifiers)
