摘要: 正 自1970年T.Y.Chang報道了光泵CH3F遠紅外激光器以來,至今已發(fā)現(xiàn)有幾十種工作物質,可在遠紅外波段產生1000多條激光線。遠紅外激光器有廣泛的應用,在等離子體診斷中,通過Thompson散射,可確定Tokamak中離子密度和溫度;在半導體中,可用來確定載流子濃度和雜質濃度;作為標準波長,可構成頻率鏈的一環(huán);在軍事上,遠紅外激光可用于亞毫米通訊;用遠紅外激光照射石英晶體,可產生頻率為幾THz的聲子,在

Abstract: An optically pumped FIE pulse laser is described. The pumping source is a tunable TEA CO2 laser with a grating. The output energy of the TEM00 mode is about 1J at 9P(20) and 9R(22) lines.This laser is of a super-radiant structure. The absorbent cell is made of a quartz tube 2m long and 20 mm ID.FIR laser action has been obtained in both CH3F and D2O. Output energies being 0.5 mJ at 496m and 0.55 mJ at 385m respectively. -
