摘要：

Spectroscopic measurements and analysis of diode laser-pumped operation of Tm, Ho:YAG at 2. 1 mu m at room temperature have been performed. The peak effective stimulated emission cross section is measured to be 9 multiplied by 10**-**2**1 cm**2 at 2. 091 mu m and the upper state lifetime is 8. 5 ms. Under diode laser pumping, thresholds of 4. 4 mW of absorbed power and slope efficiency of 19% have been demonstrated. Calculations of threshold power are performed based on the spectroscopic measurements. An energy transfer upconversion process is identified which leads to a sublinear rise in upper-state population with pump power.
