High optical gain laser media-based on chalcone compound derivatives

A method of laser production, the method comprising:

• providing energy to a gain medium so that the gain medium emits a laser in a range of 525-580 nm via amplified spontaneous emission (ASE), wherein
• the gain medium comprises a first solvent and a compound dissolved therein,
• the compound has a concentration of 0.1-8.0 mg/mL in the gain medium,
• the compound conforms to formula (1):
• where R1, R2, R3, R4, R5 and R6 are each independently hydrogen or an alkyl group or a substituted heteroalkyl group having 1 to 6 carbon atoms.

A laser device, comprising:

• a medium container;
• a gain medium contained in the medium container and configured to receive energy to emit a laser via amplified spontaneous emission (ASE), the gain medium comprising a compound in solid state and no solvent;
• and
• optics configured to direct the laser, the optics including no optical resonator around the gain medium,
• wherein the compound conforms to formula (1):
• where R1, R2, R3, R4, R5 and R6 are each independently hydrogen or an alkyl group or a substituted heteroalkyl group having 1 to 6 carbon atoms.
