Abstract
A laser amplifier for a green laser pulse includes at least one gain medium doped with praseodymium and at least one gallium nitride based diode laser for pumping the gain medium. A green seed laser pulse going through the gain medium becomes an amplified green laser pulse.
Claims18
A laser amplifier system for a green laser pulse, the laser amplifier system comprising:
- at least one gain medium doped with praseodymium and at least one gallium nitride based diode laser for pumping the gain medium, whereby a green seed laser pulse going through the gain medium becomes an amplified green laser pulse, wherein the amplified green laser pulse has a pulse duration within the range between 0.6 picosecond and 30 picoseconds in full width at half maximum.
A method of laser pulse amplification, the method comprising:
- providing a green laser pulse;
- providing at least one gain material doped with praseodymium;
- pumping the gain material by at least one gallium nitride based diode laser;
- and
- having the green laser pulse go through the gain material, such that the green laser pulse becomes an amplified green laser pulse, wherein the amplified green laser pulse has a pulse duration within the range between 0.6 picosecond and 30 picoseconds in full width at half maximum.
