As a new generation of functional ionic liquid, amino acid ionic liquids（AAIls） have the ability to form strong hydrogen bonds, dissolving the DNA, cellulose and other carbohydrates, so it can be widely used as chiral solvents and new functional materials in life science research and the pharmaceutical industry. This paper we report that the enthalpies of solution and the density for [C4mim][Ala] were measured at（288.15 to 308.15 ± 0.01） K with an interval of 5 K by a solution-reaction isoperibol calorimeter and an Anton Paar DMA 4500 oscillating U-tube densitometer. The values of the standard molar enthalpy, ΔsolHmθ, and the apparent relative molar enthalpy, φl, of solution for [C4mim][Ala] were obtained in terms of Archer’s method. The standard molar heat capacity of solution, ΔCp,mθ = 590 J·K-1·mol-1, for [C4mim][Ala] was obtained from the slope of the straight line of ΔsolHmθ vs.（T – 298.15） K. The apparent relative molar heat capacity of various molalities [C4mim][Ala] were estimated by Archer’s theory and Paulechka’s method. In addition, the hydration enthalpy of the alanine anion [Ala]-, ΔH–（[Ala-]） = – 395 k J·mol-1, is obtained. The values of standard molar enthalpies of solution and the density for [C4mim][Ala] are listed in following table: T / K 288.15 293.15 298.15 303.15 308.15 –ΔsolHmθ / k J·mol-1 63.08 ± 0.04 59.99 ± 0.05 56.47 ± 0.03 54.00 ± 0.04 51.33 ± 0.04 ρ/g·cm-3 1.09951 1.09634 1.09317 1.08998 1.08998

By using the ultrasound-assisted liquid phase exfoliation method, Bi_2Te_3 nanosheets are synthesized and deposited onto a quartz plate to form a kind of saturable absorber(SA), in which nonlinear absorption properties around 2 μm are analyzed with a home-made mode-locked laser. With the as-prepared Bi_2Te_3 SA employed,a stable passively Q-switched all-solid-state 2 μm laser is successfully realized. Q-switched pulses with a maximum average output power of 2.03 W are generated under an output coupling of 5%, corresponding to the maximum single-pulse energy of 18.4 μJ and peak power of 23 W. The delivered shortest pulse duration and maximum repetition rate are 620 ns and 118 k Hz under an output coupling of 2%, respectively. It is the first presentation of such Bi_2Te_3 SA employed in a solid-state Q-switched crystalline laser at 2 μm, to the best of our knowledge. In comparison with other 2 D materials suitable for pulsed 2 μm lasers, the saturable absorption performance of Bi_2Te_3 SA is proved to be promising in generating high power and high-repetition-rate 2 μm laser pulses.
