Ho:Tm:YLF

Ho:Tm:YLF crystal is 2μm laser crystal with Tm ion sensitized. Conveniently pumped at 792nm, 2.05μm linearly polarized beam is output. Working mode is: First, Tm ion absorbs 792nm pump light energy, and transfers the energy to upper laser level of Ho ion by non-radiative transition, then Ho ion emits laser.

product description

Ho:Tm:YLF crystal is 2μm laser crystal with Tm ion sensitized. Conveniently pumped at 792nm, 2.05μm linearly polarized beam is output. Working mode is: First, Tm ion absorbs 792nm pump light energy, and transfers the energy to upper laser level of Ho ion by non-radiative transition, then Ho ion emits laser. The advantage of above working mode is simple structure and high efficiency of laser, so it contributes to miniaturization of laser. But the defect is that the crystal must bear higher heat loss, therefore it is unsuitable for high power laser output.

■ Advantages of Ho:Tm:YLF Crystals：

Linearly polarized output beam

Little heat effect while laser

Conveniently LD pumped

Suit to miniature compact laser
