  ir-fel
We have been proposing a new photo acoustic spectroscopy (PAS) method with an infrared free electron laser (IR-FEL).
      
The IR-FEL is a continuous tunable laser in the lasing wavelength in an finger-print wavelength region with high peak power.
      
The IR-FEL resonantly induce the specific molecular vibration of the samples, resulting casue the photo acoustic pheneomena with high sensitivity.
      
Thus, the new PAS method with the IR-FEL is high sensitive analysis method applicable to low absorbance measurement.
      
In addition, we construct an imaging system of the FEL-PAS to make a map of the PAS signal with a high spatial resolution that is a diffraction limit of the IR-FEL.

AbstractByuse of modified FELOS(free electron laser oscillator simulation)code,3D short pulsesimulations of waveguide FEL oscillator were done to testify the feasibility of FIR FEL underconsideration in CIAE(China Institute of Atomic Energy).The set of parameters of CIAE FELare:optical wavelength 200um,.e-beam current 15A, emjttanee 0.022cm·rad, micropulse length50ps,wiggler length 50 × 3cm, magnetic intensity 0.144T, output coupler 5%, In this paper,we i-troduce the situation of CIAE FEL oscillator and present the preliminary view of optical power,small signal gain,spectrum and optical 3D profile. The result of 25% small signal gain is ob-tained (Fig.2),and the phenomenon of optical pulse contraction from 85ps to 10ps is observed(Fig.5).The transverse profile of optical amplitude is cosine in waveguide direction(Fig.6),which suggests that fundamental mode is still dominant in waveguide condition. We also calcu-late the influences of electron micropulse time jitter,emittance and current on the optical powerand small signal gain. It shows that the time jitter of ± 10ps comparing 50ps duration of the elec-tron nucropulse is permissible for lasing which degrades small signal gain and laser powerlittle(Fig. 2 and Fig.7a).The e-beam current and emittance influence the small signal gainmuch, and therefore are crucial to the lasing of the FEL oscillator

For far-infrared FEL, it was found that the diffractive loss is so large that it is half of total loss due to the longer wavelength using hole-coupled resonator. By changing the size of the hole, the diffractive loss can't be reduced efficiently. To improve the quality of resonator, the simulation and design of the CAEP FIR FEL with inserted scraper output coupler had been made with the help of our 3D FEL oscillator code.

For far-infrared FEL, it was found that the diffractive loss is so large that it is half of total loss due to the longer wavelength using hole-coupled resonator. By changing the size of the hole, the diffractive loss can't be reduced efficiently. To improve the quality of resonator, the simulation and design of the CAEP FIR FEL with inserted scraper output coupler had been made with the help of our 3D FEL oscillator code. It is proved that the inserted scraper is effective and applicable for the FIR FEL. Using inserted scraper output coupler, the optical cavity Q can be tuned freely. The saturated power, the net gain and the coupling efficiency are evaluated as a function of the scraper radius and the distance between scraper and the center of mirror.

 模拟了边耦合输出用于FIRFEL的可实用性,证明这种输出方式适合于远红外FEL。分析且模拟了光腔各种输出参数(如输出功率、腔增益、耦合效率等)随输出镜尺寸及位置的变化规律,找出了最佳的输出镜尺寸及位置。并对谐振腔有漂移管和无漂移管两种情况进行了比较。通过移动或者更换输出镜(输出反射镜),改变输出镜尺寸和位置,可以灵活地选择和调节光腔的Q值。能适应实验不同阶段的需要:例如在实验初期可以提高Q值,增大净增益;而在做饱和实验时可以增大输出,使输出功率最大。
