摘要

我们提出了一种谐振二极管泵浦Tm:YAG激光器，工作在2036 nm，使用体积布拉格光栅进行波长稳定。该激光器利用谐振二极管在1.69 \({\upmu }\) m处的泵浦，在2 \({\upmu }\) m附近的高大气透射光谱区域实现了高效发射。尽管对发射光谱的翼部进行了操作，但仍获得了高达4.6 W的输出功率，斜率效率为49%. In a Q-switched regime, output pulses with an energy of 0.8 mJ and a duration of 360 ns were achieved with performance constrained by the chosen components. The results highlight the potential of compact resonantly diode-pumped 2 \({\upmu }\)m Tm\(^{3+}\) laser systems for applications requiring efficient wavelength-specific sources, such as LIDAR and atmospheric sensing.

Resonantly diode-pumped Tm:YAG laser for efficient 2036 nm generation

We present a resonantly diode pumped Tm:YAG laser, operating at 2036 nm, wavelength-stabilized using a volume Bragg grating. This laser takes advantage of resonant diode pumping at 1.69 \({\upmu }\)m to achieve efficient emission in the high atmospheric transmission spectral region near 2 \({\upmu }\)m. Despite operation on the wing of the emission spectrum, an output power of up to 4.6 W was obtained with a slope efficiency of 49%. In a Q-switched regime, output pulses with an energy of 0.8 mJ and a duration of 360 ns were achieved with performance constrained by the chosen components. The results highlight the potential of compact resonantly diode-pumped 2 \({\upmu }\)m Tm\(^{3+}\) laser systems for applications requiring efficient wavelength-specific sources, such as LIDAR and atmospheric sensing.
