Small Design Changes Can Pump Up Ti:Sapphire Laser Power

Facebook X LinkedIn Email
Newly commercialized solid-state pump lasers offer great promise in Ti:sapphire systems but require some system design changes, especially in the area of thermal lensing, to realize their full potential.

Marco Arrigoni, Coherent Inc.

Ti:sapphire laser oscillators and amplifiers are the dominant sources for ultrafast applications because they can deliver ultrashort (<100 fs), widely tunable pulses and high pulse energies at various repetition rates. No other active medium, either available now or on the horizon, can match their performance. Frequency-doubled, diode-pumped, solid-state green lasers are essential components in any Ti:sapphire ultrafast system. CW versions pump both the oscillators and high-repetition-rate (>50 kHz) regenerative amplifiers, and Q-switched models pump regenerative and/or multipass...Read full article
