Features

Broad transparency range from 160nm to 2600nm.

High damage threshold.

Applications

•　 A quite high overall conversion efficiency and 540-1030nm tunable wavelength range were obtained with OPO pumped at 355nm.

      •　Type I OPA pumped at 355nm with the pump-to-signal energy conversion efficiency of 30% has been reported.
      •　Type II NCPM OPO pumped by a XeCl excimer laser at 308nm has achieved 16.5% conversion efficiency, and moderate tunable wavelength ranges can be obtained with different pumping sources and temperature tuning.
      •　By using the NCPM technique, type I OPA pumped by the SHG of a Nd:YAG laser at 532nm was also observed to cover a wide tunable range from 750nm to 1800nm by temperature tuning from 106.5℃ to 148.5℃.
      •　By using type II NCPM LBO as an optical parametric generator (OPG) and type I critical phase-matched BBO as an OPA, a narrow linewidth (0.15nm) and high pump-to-signal energy conversion efficiency (32.7%) were obtained when it is pumped by a 4.8mJ, 30ps laser at 354.7nm. Wavelength tuning range from 482.6nm to 415.9nm was covered either by increasing the temperature of LBO or by rotating BBO.

Frequently Asked Questions

What is LBO?

LBO (Lithium Triborate - LiB3O5) is a crystal material used for Second Harmonic Generation (SHG) of 1064nm high power lasers and Sum Frequency Generation (SFG) of 1064nm laser source to achieve UV light at 355nm.

What are the advantages of LBO?

LBO has a broad transparency range from 160nm to 2600nm, high optical homogeneity, high damage threshold, wide acceptance angle and small walk-off, and is phase matchable in a wide wavelength range.

What are the applications of LBO?

LBO can be used for OPO and OPA pumping, achieving a high overall conversion efficiency and tunable wavelength range. It can also be used for optical parametric generation and critical phase-matched BBO as an OPA, achieving a narrow linewidth and high pump-to-signal energy conversion efficiency.

What is the thermal expansion coefficient of LBO?

The thermal expansion coefficients of LBO are αx=10.8x10-5/K, αy=-8.8x10-5/K, and αz=3.4x10-5/K.

What is the damage threshold of LBO?

The damage threshold of LBO is greater than 10 GW/cm2 for 1064nm, TEM00, 10ns, 10HZ (polished only), greater than 1 GW/cm2 for 1064nm, TEM00, 10ns, 10HZ (AR-coated), and greater than 0.5 GW/cm2 for 532nm, TEM00, 10ns, 10HZ (AR-coated).
