CW Pumping Source P720
This compact laser pumping source consists of three water-cooled diode laser bar stacks, arranged radially around a central cavity suitable for accommodating a crystal laser rod as Nd:YAG. It delivers excellent gain uniformity and lensing performance. The rod pumped length of 46 mm is much shorter than other similar products existing in the market. This is advantageous for regenerative amplifiers, since higher energy is available before self-focusing appears. The pumping laser diodes are mounted using our solder-free Clamping™ technology.

- Other active media on request.
- The optimum water temperature depends on the operation current and water flow. It is recommended to measure the wavelength of the diode by using a spectrometer, so that water temperature is changed to achieve 808 nm for optimum pumping.
