Description

Ti Sapphire Laser Crystal is the most widely used laser crystal for tunable and ultrashort pulsed lasers. It combines the excellent thermal, physical, and optical properties of sapphire with large gain and emission bandwidths. Wider gain means shorter pulses. The laser built on it is the Ti-sapphire laser.

Ti Sapphire Laser Crystal tuning range

Large emission bandwidth tunes across hundreds of nanometers. High damage threshold and high saturation power let it handle intense pulses. One crystal serves both tunable CW lasers and femtosecond systems. Chirped-pulse amplification starts with a Ti:sapphire oscillator. The same bandwidth supports wavelength tuning without changing crystals.

Ti Sapphire Laser Crystal pumping

The absorption band centers at 490 nm. Suitable pump sources include argon-ion lasers, frequency-doubled YAG(Nd) and YLF, and copper vapor lasers. Modern systems often use frequency-doubled Nd lasers as pumps. The 3.2 us fluorescence lifetime allows effective pumping by short pulse flash lamps in powerful laser systems.

Typical applications

Ultra-fast femtosecond pulsed lasers. Wavelength tunable continuous wave lasers. Spectroscopy labs rely on its tunability for pump-probe experiments. Multiphoton microscopy uses its femtosecond pulses for deep imaging. For the classic 1064 nm workhorse, see our Nd YAG Laser Crystal.
