Abstract

See full text

In some embodiments, the instant invention provides for a system that includes at least the following components: (i) an Alexandrite laser pumping subsystem; where the Alexandrite laser pumping subsystem is configured to: 1) produce wavelengths between 700 and 820 nm, and 2) produce a pump pulse having: i) a duration between 1 to 10 milliseconds, and ii) an energy measuring up to 100 Joules; where the Alexandrite laser pumping subsystem includes: 1) an optical fiber, and 2) a Lens system, (ii) a Thulium doped Yttrium Aluminum Garnet (Tm:YAG) laser subsystem; where the Tm:YAG laser subsystem includes: 1) a Tm:YAG gain medium, 2) a rod heat sink, and 3) at least one cooling device, (iii) a wavelength selecting device, where the wavelength selecting device is configured to deliver a wavelength between 1.75 microns to 2.1 microns; and where the system is configured to produce a high energy conversion efficiency.
