Titanium-doped sapphire (Ti:sapphire) crystals combine supreme physical and optical properties with broadest lasing range,it is the most widely used Laser Crystal for widely tunable and ultrashort pulsed lasers with high gain and high power outputs. It's indefinitely long stability and useful lifetime added to the lasing over entire band of 660-1050 nm challenge "dirty" dyes in variety of applications. Medical laser systems, lidars, laser spectroscopy, direct femtosecond pulse generation by Kerr-type mode-locking - there are few of existing and potential applications.

The absorption band of Ti:Sapphire centered at 490 nm makes it suitable for variety of laser pump sources - argon ion, frequency doubled Nd:YAG and YLF, copper vapour lasers. Because of 3.2 µs fluorescence lifetime Ti:Sapphire crystals can be effectively pumped by short pulse flashlamps in powerful laser systems. Coupletech Co., Ltd. supplies high quality Ti:Sapphire, under control all the specs with our crystal, including inside quality, absorption, FOM data etc..

Applications:

The tunable wavelengths that cover a broad range from 700 to 1000 nm make Ti:Sapphire an excellent substitute for dye lasers in many applications;

Doubling by NLO crystals such as BBO in an ultra-thin, Ti:Sapphire can be used to generate UV and DUV (up to 193 nm ) laser with ultrafast pulses below 10fs;

Ti:Sapphire is also widely used as the pumping source of OPOs greatly to expand the tunable range.
