Mira 900 Ti Sapphire

The Coherent Mira 900 is a Ti:sapphire laser system that includes a Mira 900 controller, a Verdi V-6 diode pump laser, a Verdi 6W power supply, an operators manual, and small parts and accessories.^[1]

In a Ti:sapphire laser, optical pumping is typically provided by a diode-pumped solid-state laser emitting in the green wavelength range. The pump light excites the titanium ions in the sapphire crystal, producing gain over a wide band of near-infrared wavelengths. Tuning elements such as birefringent filters or prisms select the desired output wavelength.

In precision optics and semiconductor metrology environments, tunable lasers serve as excitation sources for spectroscopic techniques, as illumination sources for inspection systems, and as seed sources for optical parametric amplifiers. The laser is positioned as a light-source subsystem that feeds into measurement or processing tools rather than as a standalone fabrication step.

Upstream processes include the manufacture of the laser gain medium and pump diodes, while downstream uses involve integration into a microscope, spectrometer, or lithography tool. The laser itself requires external cooling and stable environmental conditions to maintain wavelength accuracy and power stability.

In industrial precision optics, these lasers perform tasks such as thin-film ablation, laser-induced breakdown spectroscopy, and the testing of optical components for transmission and damage thresholds.
