Nd:Sr[sub 5](VO[sub 4])[sub 3]Cl has been successfully lased using a Ti:sapphire pump laser operating at 810 nm. A slope efficiency of 52% for the 1.065 [mu]m laser line and a lasing threshold of only a few tens of milliwatts have been measured. These favorable results are comparable to another Nd-doped vanadate apatite, Sr[sub 5](VO[sub 4])[sub 3]F. A brief survey of the spectroscopy of Nd[sup 3+] in Sr[sub 5](VO[sub 4])[sub 3]Cl, Sr[sub 5](VO[sub 4])[sub 3]F, and Ca[sub 5](VO[sub 4])[sub 3]F reveals properties which suggest the vanadate-based apatite crystals as a whole may represent a useful new class of Nd-laser hosts.
