Claims: I claim:

1. A method for the production of nascent chlorine by irradiating COCl.sub.2 in admixture with H.sub.2 /D.sub.2 to produce HCl or DCl in an excited vibrational state which lases, said method comprising:

(i) preparing a homogeneous admixture of COCl.sub.2 and H.sub.2 /D.sub.2 ;

(ii) metering said admixture of COCl.sub.2 and H.sub.2 /D.sub.2 into a properly conditioned laser cell to achieve a predetermined pressure from about 25 to about 200 torr; and

(iii) irradiating said admixture of COCl.sub.2 and H.sub.2 /D.sub.2 for a predetermined time period with the P.sub.54 line of a cw CO.sub.2 multiline laser operating at a predetermined power level to effect dissociation of COCl.sub.2 to produce nascent chlorine atoms which immediately react with H.sub.2 /D.sub.2 present to produce HCL or DCl in an excited vibrational state which lases.

2. A method of claim 1 wherein said homogeneous admixture is COCl.sub.2 and H.sub.2 ; said predetermined pressure of said homogeneous admixture in said laser cell is about 100 torr; said predetermined power level of said cw CO.sub.2 multiline laser is about 150 watts; said predetermined time of irradiating is about one second; and wherein HCl is produced in an excited vibrational state which lases.

3. The method of claim 1 wherein said homogeneous admixture is COCl.sub.2 and D.sub.2 ; said predetermined pressure of said homogeneous admixture in said laser cell is about 100 torr; said predetermined power level of said cw CO.sub.2 multiline laser is about 150 watts; said predetermined time of irradiating is about one second; and wherein DCl is produced in an excited vibrational state which lases.
