摘要： A regenerative amplifier system that is optimized for low-gain gain media is provided. The system is configured to include a minimum number of intra-cavity elements while still eliminating the leakage of the seed pulses from the output beam. In addition, the contrast ratio of the amplified pulses is increased even considering the long build-up time that is required in low-gain regenerative amplifiers. This is accomplished using a single Pockels cell between the oscillator and amplifier to select a single seed pulse for the cavity, instead of using a Faraday isolator. This directs the unwanted seed pulses in a separate direction from the output pulse. When the amplified pulse exits the cavity, it is directed in a direction away from the oscillator by the same Pockets cell. Only one additional Pockels cell and one polarizer are required inside the regenerative amplifier cavity.
摘要翻译：提供了针对低增益增益介质进行了优化的再生放大器系统。该系统被配置为包括最小数量的腔内元件，同时仍然消除种子脉冲从输出光束的泄漏。此外，即使考虑到低增益再生放大器所需的长的积聚时间，放大脉冲的对比度也增加。这是使用振荡器和放大器之间的单个Pockels单元来实现的，以便为腔体选择单个种子脉冲，而不是使用法拉第隔离器。这将不需要的种子脉冲与输出脉冲分开的方向。当放大的脉冲离开空腔时，它通过相同的口袋单元被导向远离振荡器的方向。再生放大器腔内只需要一个附加的Pockels单元和一个偏振器。

摘要： An optical system has a diode pump source, and a gain media made of a material with an anisotropic absorption. The gain media is cut at an angle to produce substantially polarization- independent absorption of a pump beam. An optical coupler is positioned between the diode pump source and the gain media. The optical coupler produces a pump beam that has substantially equal amounts of pump power along any two orthogonal axis that are orthogonal to the pump beam in the gain medium. The wavelength range allowed for the pump source is extended.
